In the automotive sector, development in chassis and body of vehicles is driven by two main aspects, safety, and lightweighting. As the body is the first point of impact during a car crash, modern designs have incorporated features such as crumple zone to absorb most of the initial impact, reducing the force that will reach the passengers. With this in mind, it is essential to understand material behavior under high strain rate, especially during development cycles of metals, alloys, and composites that may be used in chassis or body design. On the other hand, lightweighting provides better fuel economy for the car, decreases component wear and hence provide a much more competitive product overall. Therefore, characterizing how material properties change under high strain rate is important in order to find the optimum design maximizing safety and lightweighting.
