High Strain Rate Mechanics of Materials

This lecture covers experimental methods for determining high strain rate (HSR) behavior in materials, focusing on wave propagation and stress waves. It discusses types of elastic waves, decay characteristics, wave velocity versus particle velocity, and stress waves energy and decay. The lecture also explores stress equilibrium in solids, acoustic impedance, wave interaction at interfaces, and the influence of impedance on wave reflection and transmission. Additionally, it delves into the momentum trap technique, strain gage signals, and the stress-strain response of ceramics at high strain rates.
