Adiabatic Shear Bands in Simple and Dipolar Plastic Materials

Abstract

A simple version of thermo/viscoplasticity is used to model the formation of adiabatic shear bands in high rate deformation of solids. The one- dimensional shearing deformation of a finite slab is considered. Equations are formulated and numerical solutions are found for dipolar plastic materials. These solutions are contrasted and compared with previous solutions for simple materials. Keywords: Shear bands, Viscoplasticity, High rate deformation.
