Constitutive Features of Solids at Shock-Wave Loading Rates

Abstract

Solid subjected to high-velocity impact or explosive loading exhibit unusual transient and post-shock properties during the extremely brief period associated with the shock-wave risetime and release. These features can include a unique solid-state shock viscosity behavior, anomalous transient shock- hardening effects, heterogeneous shear effects during the shock risetime, and shock-induced solid state and metallurgical transformations. Improved methods in time-resolved instrumentation have been critical in the emerging understanding of these constitutive features. An increasing sophistication in physical and computational modeling is required to incorporate these effects in applied problems of dynamic solid mechanics.
