Abstract

Abstract

By accounting for the effects of temperature and damage on material parameters and the coupled effects of temperature and damage on the plastic deformation, a general explicit form and a specific incremental form of a thermal-plastic constitutive relation have been obtained based on the internal variable theory. For the problem of imploding load induced spallation in spherical shell, a set of equations have been developed and numerically solved with finite difference method.
