High Strain Rate Mechanics: Material Behavior Dynamics

This lecture introduces the study of material behavior under rapid forces, focusing on wave propagation, dynamic stress-strain responses, and the impact-induced damage in materials. It covers topics such as dynamic deformation of metals and ceramics, response of soft and biological materials, and computational models. The instructor discusses the transition from ductile to brittle behavior under high strain rates, the influence of inertial effects on material response, and the propagation of stress waves. Additionally, the lecture explores the types of elastic waves, wave velocities in solids, and the decay of stress waves. Students will gain insights into the dynamic behavior of materials and the implications of high strain rate mechanics.
