Material Behavior in High Speed Impact

Abstract

A gas gun facility was established for the purpose of studying effects of impact in solids. Research was conducted on the dynamic strength of several materials with the goal of relating macroscopic effects to atomic mechanisms. It was discovered that some crystals (lithium fluoride) that are relatively soft and plastic under usual conditions can support extremely large stress differences for short periods of time. Further, the observed strength cannot be explained by usual theories applicable to low strain rate behavior.
