Why Mechanical Engineering is Important

If you believe mechanical engineering might fit your future, and you are interested in engineering non-trite objects, learn why this discipline is so important in 2021.

Table of Contents

What Is Mechanical Engineering?

Mechanical Engineering (ME) can be considered as an art of implementing problem-solving skills and techniques into the manufacturing and design of various objects. In simple terms, such a worker spends time on creative design and analytics to make a concept a real thing. At the same time, ME is a diverse and versatile field of engineering. You should possess knowledge of physics, and maths. Depending on your specialization, and career choice, you should also know aerospace, electrical, civil, and chemical basics. ME can be found in pretty everything we have in our life including mobile gadgets, biomedical technologies, aircraft and even power plants. You won’t also avoid the understanding of economics, where you have to deal with the component costs. 

When being enrolled in educational establishments to pursue mechanical engineering, students primarily learn about solid and fluid mechanics, materials, thermodynamics, heat transfer, control, product design alongside manufacturing processes. To make a student even more presentable, there will be courses dedicated to professional communication and business management.

Importance of Mechanical Engineering

Let’s first start by revealing the skills you get by studying this discipline. Everything you acquire can be considered transferable. It means that your skills and knowledge can be implemented in a variety of industries and businesses. 

• Problem-solving . Mechanical engineering stands for finding better ways of doing typical things. You do not just engineer the things you use every day, but you work on developing better and better versions of the previous models taking into consideration all the previous problems, malfunctions, and successes;
• Teamwork . Such workers are usually linked to join huge networks. You collaborate daily with others, share expertise and ideas to come up with something excellent;
• Technical skills . You build knowledge in physics, maths, and other related disciplines. In simple terms, you are like a jack of all trades who can share his ideas on many subjects;
• Decision making . Another helpful skill is the ability to make right and not rash decisions. You are not afraid of risks and can work under huge pressure.

As for the studying areas, you will definitely gain knowledge in computer applications, electricity, design and manufacturing, robotics, and artificial intelligence among others. Still interested? Looking ahead, let’s also say that you have vivid prospects for receiving a very decent salary uncomparable to other specializations. 

Then, the importance lies in the prospects. The future prepares for us new challenges, and we won’t surely enjoy every day without facing some catastrophes or other environmental issues. Sorry for such negativity. Yet, mechanical engineers are one of those workers who are always in demand when it comes to developing and engineering the solutions and constructions to protect populations from tsunamis, tornadoes. A great example is Japan where such workers are well-paid and very respected. They spent years on building the constructions that could not only help the country to minimize the harm of tsunamis but also receive early alerts when such events are possible to occur. The same concerns tornadoes and the modern building protection solutions that help to leave a house stable without building it from scratch.

Do not be shocked but it could be also visible thanks to the pandemic. There were many hospitals built within days or weeks thanks to mechanical engineering technologies. Many countries where hospitals were occupied with patients required additional facilities, and they got them thanks to such specialists.

What else? Mechanical engineering can help us reach other planets. As was said above, the best options to experience the workers’ potential are NASA and SpaceX. ME specialists there spend days on building and designing the rockets, so they won’t only enter space but also come back without any damages. Yes, it is a collaborative work of teams, however, mechanical engineers are the ones who play an important role in engineering a machine that can withstand many space obstacles and protect the astronauts. As you may guess, the pressure on such workers there is also high, because they literally can make one mistake and put the whole mission at great risk. 

Finally, mechanical engineers also work as professors on other faculties. They help students understand the values of the subject and implement the basic knowledge in their own specializations. For example, physics discipline in conjunction with mechanical engineering can help a student build a career in various fields such as pharmaceutical engineering, IT, and industrial fields with oils.  It would be fair to say that you cannot simply learn it all by signing up for online courses. Yes, there are such courses, however, they serve only as training or additional knowledge tools where you update your existing knowledge from the college/university. You should study it only in higher educational establishments. Check online scholarships including overseas opportunities because they are many due to the demand for the specialization.

If during the studying, you experience some hurdles with engineering homework, you can deal with it by relying on engineering assignment help where experts and helpers who alone graduated in such disciplines assist with projects of any complexity. The specialists take any deadlines and ensure you receive high-quality assistance. “My project needs some research” – all the requirements are met. So, no worries.

Why Writing Matters

Why Writing Matters in Mechanical Engineering

"Mechanical engineers utilize writing daily to communicate design ideas, create manufacturing instructions, report test results, verify project progress, create user manuals, and disseminate information."

~Brooks Byam, Department Chair

When people think of mechanical engineering, they usually think about mathematics, science, technology, new products, and economic growth. Unfortunately, they do not realize the importance of writing in engineering. Mechanical engineers utilize writing daily to communicate design ideas, create manufacturing instructions, report test results, verify project progress, create user manuals, and disseminate information. The audiences that these documents communicate to are also wide. Engineers must be able to effectively communicate complex topics and ideas to other engineers, business personnel, marketing people, and the public. Writing provides an essential means of communication.

Typical Writing Assignments

In the Mechanical Engineering program at SVSU, students have a variety of writing assignments. Students must write five to seven laboratory reports for courses with a laboratory. Many of our courses have semester long design projects that require students to document their design calculations and decisions. These design projects range from a memo type format to a long white paper style document. In the senior design project, students must write a manual for their product and submit a design report that documents all calculations, design decisions, and test data.

Qualities of Good Writing

The same principles of good writing in literature courses apply to engineering writing. There are a few differences. All documents are written in the third person, (i.e., I, me, we or us are never used). While the topics in engineering are complicated, a good engineer can write an appropriate document for the audience they are addressing.

Appropriate Types of Evidence & Support

Evidence in engineering consists of testing data, mathematical solutions, and publications. Citation of publication from peer-reviewed journals or technical publications are the accepted sources of written evidence. These sources spend a considerable amount time and effort ensuring the information published meets the rigorous standards of scientific inquiry. Peer-reviewed journals send each submitted paper to a panel of experts for review. This review ensures that the conclusions drawn are driven by trends found in the data, and checks the validity of the experimental approach and calculations. Technical publications have a staff of professionals that provide this evaluation.

Citation Conventions

Citation formats very from journal to journal. However, journals either use a numbered endnote style of citation or a citation style footnote. Parenthetical citation is NEVER used. Citations of websites are never acceptable.

Special Comments

Due to the strong mathematical nature of many reports, engineers must be familiar with using the equation editors in their word processing package.

Mechanical engineering driven by innovation for the future

Mechanical engineering is one of the most important pillars of the global economy and is currently facing enormous challenges now and in the future..

Mechanical engineering is one of the most important pillars of the global economy – and it is currently facing enormous challenges: new technologies, increasing customer expectations, but also economic and political uncertainties are changing the industry from scratch and are demanding innovative ideas and products. We therefore discussed the trends and developments in mechanical engineering with a panel of experts who also ventured a look into the future of the sector.

About the panelists:

• Thomas Ameis joined the Helukabel subsidiary EKD Systems as technology manager in October 2022.
• Dr. Sebastian Eisele is managing director of Eisele Elektronik GmbH.
• Andreas Muckes has been working at Helukabel as a global segment manager drag chain systems since August 2023.
• Holger Wennrich joined Helukabel in 2007 and has held a variety of positions, including subsidiary manager in Italy and China.

Industry, and particularly mechanical engineering, is a long-living and special tradition in Germany. What do you associate with the sector?

Andreas Muckes: For me, mechanical engineering, particularly here in Germany, has always been inspired by a certain spirit. There have always been things that were claimed to be impossible – and then a Mr. Siemens or Daimler or Bosch came along and said “It is possible!” and made it so. In my opinion, it’s this ambition, the creativity to think in new dimensions and the ability to adapt to ever-changing circumstances which are the essential attributes and virtues that have kept mechanical engineering alive and kicking in Germany to the present day – and will do so in the future too, I hope.

Holger Wennrich: It’s also why German machine builders have a very good reputation abroad, particularly with respect to quality. When talking to colleagues and clients abroad, I often hear that machinery is made in Germany according to the “as good as possible” principle, whereas in the rest of the world the “good enough” principle usually applies. This can be a problem, but it can also be seen as an opportunity.

Muckes: There are an amazing number of “hidden champions” in mechanical engineering who are absolutely best-in-class in their specialist area. It’s very seldom though that the public has heard of these companies – after all, when people buy cars, sports shoes or other goods they’re not usually interested in the machines that produce them.

Dr. Sebastian Eisele: By contrast, people buying and using machinery have definitely heard of these companies. For them, of course, quality and reliability are among the most important purchase criteria. But other factors also play a role. For example: how much space does the machine need in my factory? Can it be connected to other machines? Is it easy to operate? These are questions that manufacturers need to think about early on in the development process.

Alongside the traditional creative spirit, it is mainly topics such as productivity, efficiency and flexibility that influence the development of mechanical engineering. What, in your opinion, are the most important drivers of innovation in the sector?

Wennrich: For me, flexibility is the most important trend. The size of production runs is declining in almost every sector. Manufacturers are being forced to produce more cost-effectively with bigger variances. They need the appropriate machinery as well as new manufacturing concepts with features such as networking and digitalization to do this.

Eisele: This demand for more flexibility is also driven by increasing personalization – not only for consumer goods but also in mechanical engineering itself. In the past, machine builders developed and sold standard products. These times are now over. Today customers know exactly what they want and are demanding more and more individual modifications – even for machinery. This means suppliers also have to be much more flexible.

Muckes: At the same time though, the quality must be just as high, if not higher. For example, a machine tool must manufacture every part with the same precision – regardless of whether it’s making one or 50,000 parts. That adds another whole layer of complexity to the requirement profile.

The experts agreed: Flexibility and proximity to the customer are becoming increasingly important in mechanical engineering. Courtesy: Helukabel

Digitalization and networking are changing mechanical engineering from the bottom up. Which challenges and opportunities do they bring machine builders and their customers?

Thomas Ameis: I see this trend as an opportunity for mechanical engineering to prove its innovative power. If you want to be successful in this sector in the future, you have to stand out from the competition as an innovator in areas such as digitalization, networking and predictive maintenance. This is technically challenging, of course, but it also holds a lot of potential – particularly when it comes to economically viable manufacturing processes with batch sizes as small as one. New technologies such as additive manufacturing or 3D printing are offering possibilities previously undreamed of.

Eisele: It must be said here though that digitalization and networking are not exactly core competencies here in Germany. The major innovations are mostly taking place abroad. This is partly due to the high level of data protection we have here – which is undeniably important as it’s certainly advisable to handle sensitive company data carefully. On the other hand, we have to make sure we don’t miss the boat or dillydally around too much. Take AI for example: Instead of looking at the unbelievable potential of this new technology, public discussion is mostly about restricting its possibilities. I don’t think this is necessarily the right approach.

Digitalization in mechanical engineering also means installing even more sensors, controllers and other electronic components together with the relevant cabling. Which cables are mainly used for this?

Wennrich: They range from motor and servo cables for electric drives to connection and sensor cables and bus and Ethernet cables for data transmission: generally speaking, the more digitalized and automated a machine is, the greater the variety of cables. An important aspect here is the space available for installing more sensors and electrical components in the machine. As this usually remains the same, solutions that save space are becoming more and more sought-after – that means small outer diameters and bending radii.

Drag chains are often used to securely connect cables and wires to moving machine parts. What needs to be thought about during their construction and use?

Eisele: These days machinery needs to be faster and more dynamic. Increasing travel distances and speeds are putting more stress on the drag chains, something which also needs to be planned for. During this planning though, you face a dilemma between the space available and the number of cables needed. On the one hand, the machine should have lots of functions and extensive electrical fittings, on the other hand it should be as compact as possible.

Ameis: We’ve noticed this too: The number of cables is increasing due to more networking and sensor technology, but the space available for installing the drag chain is the same. It’s becoming more and more difficult to lay the cables in separate chambers in the chain. It’s important here to use the space intelligently by ensuring the cables are optimally arranged. With this internal arrangement, taking into account the installation guidelines, the maximum service life of the cables can be guaranteed.

Muckes: In addition, customers assume that the cables, connectors and chain in drag chain systems are all compatible with one another, which is certainly not always the case. Here we’re talking about mechanical and electrical components for a machine which are usually designed by different departments. Often these departments don’t communicate enough with each other and have different requirements, for example, with respect to space. As a system supplier, we are in a position to bring these departments together to solve these challenges. Customer proximity is a must for this though.

Talking about customer proximity: for many machine builders, the focus is increasingly on service concepts. What does good customer relations mean and what does a successful strategy look like in your opinion?

Eisele: One promising approach in mechanical engineering involves turnkey concepts, i.e. the provision of ready-to-use products. Companies in all sectors are complaining about the skills shortage. They don’t have enough qualified staff to commission or even operate their machines. So, anyone able to offer complete ready-to-use production lines which ideally no longer need operating staff but just technicians to service them has a clear-cut advantage. Customers are also prepared to pay extra for this. Machine builders don’t always know in advance though who’s buying their machines and exactly how they’ll be used which makes designing them difficult.

Ameis: That’s true. It’s often difficult to plan for their ambient conditions. What counts here is experience with the machines in everyday use. Geographical differences shouldn’t be underestimated. A machine in Thailand, for example, is subject to completely different temperature and humidity stresses than one in Germany. Hence, it’s a good idea to test them in various conditions beforehand.

Wennrich: Expert technical advice is and will always be extremely valuable. When it comes to cables, for example, it’s true to say that standard products are purchased where the price-performance ratio is best. However, customers prefer to purchase sophisticated products from reliable partners who know their challenges and applications well. Ideally, they’ll buy everything from this partner to simplify the procurement process.

Muckes: The purchasing department is often forced to buy according to the motto “we’ve always done it like this”, either because they’ve been integrated into the procurement process too late or the project is very urgent – and this despite there perhaps being significantly better components available on the market in the meantime. It’s also the supplier’s job to point out potential optimizations, to actively offer alternative solutions and to clearly explain their added value.

Ameis: If the customer needs a product that perhaps doesn’t exist, one possibility is for the supplier and customer to develop it together until it’s ready for serial production. This creates a long-term and stable relationship with the customer.

Another trend is the move towards more sustainable production methods and renewable energy sources. What obstacles are associated with this and how can machine builders benefit from it in the long term?

Eisele: The move to renewable energy is definitely necessary. However, the current high energy costs are proving to be a real challenge for many manufacturing industries. I think politicians have to create a better general framework to ensure Germany remains a competitive location in the future as well – other countries are making the move more successfully at the moment. A slight unraveling of the complex global supply chains is another approach that offers more sustainability. After all, the Covid pandemic made it drastically clear how little it takes to bring production to a halt. It also had a vast knock-on effect with suppliers whose upstream products were no longer needed. Many of them now find themselves in a precarious situation. And lastly, a question that also needs to be asked is: Is it really necessary to buy a product from the other side of the world rather than from around the corner just because it’s a few cents cheaper?

The turbulences in global supply chains discussed here, but also political crises and inflation mean many machine builders are facing an uncertain future. How can they best deal with these uncertainties?

Muckes: A knock-on effect of these uncertainties is more short-termism. Mechanical engineering, however, lives from the planning phase during which not only new products but also new ideas emerge. As this is contrary to the trend, I can imagine it becoming the norm in the future to work closely with suppliers as early on as the planning stage and to view the various processes through their eyes. This will make it easier to decide whether a particular process is really sensible in terms of feasibility, functionality and sustainability, and will increase the tempo of development.

Eisele: I also think long-term cooperation could be key to coping with uncertainties – for example, a partnership where the focus is on a particular type of machine. Good communication between manufacturer and supplier is particularly important here and will definitely become more so in the future.

Muckes: Another benefit of Germany as a business location is the high concentration of companies in a small area, including the so-called hidden champions. This proximity makes it easier to work in flexible partnerships. If suppliers allow customers to work with them on the required product, they also can bring creativity to the forefront.

Bearing in mind all these challenges as well new opportunities, how do you see mechanical engineering developing in the coming years?

Muckes: I think the next development stage in mechanical engineering will be one that enables even more cost-effective production and in smaller quantities, i.e. down to batch sizes of one, but in the same high quality as series production. Digitalization, networking and new technologies such as additive manufacturing will make this possible. It’s just a question now of making best use of this opportunity.

Eisele: I see a great need for improvements in Germany, as far as the general political framework is concerned – for example, by speeding up the approval process. Many companies have reservations about new developments because of the complications in obtaining the relevant approvals. This must be simplified, but not at the expense of quality. It’s also a fact that more and more production activities will be carried out by machines in future which will boost demand for them. That’s why I see a rosy future for mechanical engineering. It’s important now to consolidate resources, to know what you’re good at, to watch the market and perhaps to be more adventurous. In my opinion, there’s nothing then standing in the way of success.

Ameis: I can only agree with you there. Innovative power has always been the distinguishing feature of mechanical engineering and it will continue to ensure its success in the future too. I am convinced about that.

Why Are Ethics Important in Engineering?

• 16 Feb 2023

Engineers are vital to shaping our world. Their decisions have far-reaching consequences—typically related to risk management. As such, it’s essential for engineers to hold themselves to a high standard.

In a survey published by the International Conference on Engineering Education (IEEE) , 92 percent of respondents said ethical issues exist in engineering and could be improved. This kind of sentiment has led companies to examine their ethical standards, particularly in relation to engineering leadership.

If you’re interested in learning about how ethics shape engineering, here’s an overview of the industry’s ethical standards, why they’re important, and the role they play in leadership.

Access your free e-book today.

What Are Engineering Ethics?

Engineering ethics are principles and guidelines engineers follow to ensure their decision-making is aligned with their obligations to the public, their clients, and the industry. The National Society of Professional Engineers’ (NSPE) code of ethics outlines the standards of ethical behavior engineers should follow in their professional lives. Those include:

• Protecting public safety
• Only performing tasks they’re qualified to do
• Being honest in public communications
• Remaining faithful and trustworthy to employers
• Acting with integrity

These principles are designed to help you, as an engineer, make ethical decisions in your work and promote responsible use of industry technologies.

7 Reasons Ethics Matter in Engineering

Trust is required between engineers and the public, which is why it’s crucial for you to understand the importance of acting ethically. Here are seven reasons why ethics matter in engineering.

1. Promotes Safety

The NSPE’s code of ethics requires you to prioritize public safety in your work.

For instance, you’re expected to notify employers and clients when their judgment is overruled because of dangerous circumstances or when documents don’t conform with applicable standards. Doing so can prevent harm to individuals and communities and ensure your work meets the highest safety and reliability standards.

In addition to ethical considerations, there’s a business case for safety in the workplace. Prioritizing safety not only protects employees and customers but also improves productivity and reduces costs associated with accidents and injuries. According to Liberty Mutual’s 2021 Workplace Safety Index , U.S. employers spend more than $1 billion per week on serious, nonfatal workplace injuries.

2. Enhances Quality

Engineering ethics are also critical to improving your quality of work. According to NSPE’s code of ethics, you should only perform tasks that closely align with your education and experience.

This is important when working toward an engineering leadership position. For instance, as an organizational leader , you’ll often manage individuals who are experts in areas you know little about. You’ll need to shift from a specialist to a generalist management style by focusing on relationships, adding value by enabling work, considering the bigger picture, and relying on executive presence. The goal is to enable specialists on your team to do their highest-quality work.

The “leader as architect” concept—discussed in the Harvard Business School Online course Organizational Leadership taught by HBS professors Anthony Mayo and Joshua Margolis—refers to your role in enabling work to happen rather than doing it yourself.

“Since leaders can’t personally make those conditions happen for each person every day across a big organization, they don the hat of the architect,” Mayo says in Organizational Leadership . “And their work is to use a set of organizational components to create and sustain motivation, competence, and coordination.”

3. Improves Public Opinion

Ethics also help improve public opinion about engineering professions.

For example, the NSPE’s code of ethics requires you to be honest in your public communications through objective, truthful statements free of private interest, deception, or misrepresentation. Honesty in public relations is crucial to building trust. It’s even more critical for you as an engineer because your decisions directly affect the public’s safety and well-being.

In an era where communication skills are increasingly valued, it’s crucial to act ethically in your interactions with the public. Doing so can help improve perceptions about the engineering industry and demonstrate your commitment to ethical, responsible behavior.

4. Safeguards the Company’s Interests

Adhering to engineering ethics can also help protect your company’s interests.

The NSPE’s code of ethics discourages you from disclosing sensitive or confidential company information without explicit consent, obtaining employment or advancement with improper methods, and unethically harming other engineers’ professional reputations.

By adhering to these principles, you can help protect your firm’s interests—as well as your team's—and ensure you contribute to its success.

5. Fosters Sustainability

Engineering ethics promote sustainability by requiring you to consider your work's long-term impact on the environment and society. Additionally, sustainability is vital to modern business because it can improve your organization’s reputation, increase growth opportunities, and boost financial performance.

If you struggle to understand sustainability's context in your role as an engineer, consider the triple bottom line , a concept that asserts businesses should go beyond financial performance and measure their social and environmental impacts. If you consider profit, people, and the planet in your daily work, you’re more likely to follow the industry’s ethical standards around sustainability.

6. Protects Other Engineers

Engineering ethics aren’t just meant to protect employers, clients, and the public. They also help protect individual engineers by discouraging all industry professionals from engaging in unethical or illegal behavior for their benefit.

The NSPE’s code of ethics specifically states that “engineers shall not attempt to obtain employment or advancement by untruthfully criticizing other engineers.” It also specifies that “engineers shall not attempt to injure, maliciously or falsely, directly or indirectly, the professional reputation, prospects, practice, or employment of other engineers.”

These guidelines are especially important when considering your team’s performance and productivity. Fostering an environment that promotes employee engagement can prevent negative dynamics from corrupting your workplace.

7. Secures Company Assets

Engineering ethics help ensure your team members and organizational leaders act in ways that protect your company’s intellectual property and confidential information.

The designs, inventions, and writings created by your team are often recognized as the property of either your client or the individual responsible for those assets. You must acknowledge such ownership agreements prior to beginning work. In doing so, you can prevent theft and misuse of your company’s assets and protect its investments.

The Importance of Ethical Leadership

Leading ethically is critical to long-term success in the engineering industry. Ethical leaders model honorable behavior, set an example, and foster cultures of integrity and respect.

“A leader needs to be adaptable and step out of their comfort zone if they want to foster a culture in which others do the same,” Mayo says in Organizational Leadership .

By adhering to the tenets of ethical leadership, you can hire individuals whose principles align with your organization’s values.

“You want to look for individuals whose values, attitudes, and skills are consistent with what your organization needs and cares about,” Margolis says in the course.

Elevate Your Organizational Leadership as an Engineer

Ethics are crucial in engineering. They not only promote quality work but also encourage you to operate safely and maintain a high standard of ethical responsibility.

As an organizational leader, you often dictate your company’s culture and values. Understanding engineering ethics—and the business skills needed to apply them—is essential to your success.

By furthering your education through an organizational leadership course , you can learn how to adapt to constantly evolving responsibilities and become an effective leader .

Polyethylene terephthalate (PET) fiber-reinforced polymer (FRR) has been recently developed, which possesses a bilinear tensile stress–strain relationship and a large rupture strain (LRS) capacity. This study presents a novel approach for accurately predicting the stress–strain behavior of PET FRP-confined concrete using machine learning (ML) techniques. A comprehensive dataset comprising 154 axial compression test specimens, including both circular and noncircular cases, was utilized for training and testing ML models. Three advanced ML models, namely extreme gradient boosting (XGBoost), random forest regression (RFR), and k-nearest neighbors (KNN), were applied to predict mechanical properties for both circular and noncircular specimens. XGBoost consistently outperformed RFR and KNN, demonstrating superior accuracy in predicting stress–strain curves for both specimen types. Performance evaluation relied on key metrics such as coefficient of determination ( R 2 ), mean square error ( MSE ), root mean square error ( RMSE ), and mean absolute error ( MAE ). Furthermore, the predicted stress–strain curves generated by XGBoost were compared to experimental data and a mechanism model, highlighting the superiority of XGBoost in capturing critical curve points and emphasizing its accuracy and consistency. Moreover, feature importance analysis was carried out and it revealed that parameters like the number of PET FRP layers, fiber thickness, and corner radius significantly influenced the stress–strain behavior.

When waves are important, what is the best constitutive law for impact mitigation and how can we realize it.

Date: 

Location: , speaker: .

Particularly for high-speed impacts, the propagation of mechanical waves, affected by the properties of the material through which they traverse, can play a major role in the resulting damage incurred. This raises the question, in such regimes, if I could choose any constitutive response for the impacted material, what is the best one I could pick? For this talk, I will summarize our initial steps towards answering this question. Considering the peak transmission of kinetic energy as our figure of merit and using reduced order dynamical models, we study the interplay of impact conditions and: i) bistable elasticity, viscosity, and discreteness; ii) bilinear elastoplasticity; and iii) tailorable polynomial nonlinear elasticity. The observed difference in performance raises the further question: how can we realize materials with an identified optimal constitutive response? I will describe our initial steps to answer this latter question via the use of shape optimization of subwavelength structural motifs. The approaches described herein may find future use in impact problems considering different figures of merit, energetic regimes, and physical mechanisms, as well as different dynamical settings, unrelated to impact, potentially even outside solid mechanics.
