Abstract
A finite strain deformation formalism developed in the literature can be used to calculate Hugoniot states for isotropic materials. In the present paper, terms in the free‐energy function are retained to third order, enabling temperature‐stress‐strain relations to be determined for uniaxial shock loading for stresses up to 150 kbar in metals. Coefficients of these terms are expressed as functions of the elastic constants of the material. The theoretical Hugoniot stress‐strain curve for copper and aluminum agrees satisfactorily with experiment when the elastic constants are sufficiently accurate.This publication has 14 references indexed in Scilit:
