Impact dynamics is a research area that focuses on understanding and predicting the behavior of objects when they collide with each other or with a surface. This field encompasses a wide range of disciplines, including physics, engineering, and material science. Impact dynamics studies the factors that influence the outcome of a collision, such as the velocity, mass, and angle of impact, as well as the properties of the materials involved. Researchers in this field develop models, simulations, and experimental techniques to investigate the effects of impacts on various systems, from microscopic particles to large-scale structures. The findings from impact dynamics research have applications in fields such as automotive safety, sports equipment design, and aerospace engineering.
