Strain Rate Influences on Shock Wave Propagation in Metals.

Abstract

The theory of the propagation of shock waves, and steady waves having an invariant profile, is considered. The wave structures associated with rate independent plasticity laws are contrasted with those influenced by rate effects. Thermo-elastic plastic response is considered, and the laws are formulated so the hydrodynamic theory supplies a component of the solution when shear strength effects are significant. When rate effects are included a marked difference in the response of work-hardening and strain-hardening materials is evident. Some comments are made on the influence of material inhomogeneity.
