AAE 59000 / MSE 59700: Dynamic Behavior of Materials
Materials' responses to high-rate loading are different from their quasi-static behavior. Applications of materials in structures subjected to impact loading require the understanding of dynamic material behavior when they are loaded by impact, crash, high-speed machining, or earthquakes. This course introduces stress wave propagation in solids, high-rate experimental methods, dynamic material behavior and deformation mechanisms, and dynamic fracture.
