Abstract

The behaviour of metals under dynamic loading is described by introducing a continuum damage theory, which is also valid for nonisothermal processes. Microstructural changes are modelled by internal variables, e.g. damage due to shear bands is described with a second order tensor. Dislocation induced viscoplastic deformations are modelled using a flow rule of the overstress-type.
