Effect Of Initial Temperature On The Initiation And Growth Of Shear Bands In A Plain Carbon Steel

Abstract

We study thermomeehanical deformations of a thermally softening viscoplastic block undergoing overall adiabatic simple shearing deformations. The dependence of the specific heat, thermal conductivity and shear modulus for the material of the block upon the temperature is accounted for. It is assumed that the block has a geometric defect in the sense that its thickness varies smoothly and is 5% less at the center as compared to that at the edges where essential mechanical boundary conditions are prescribed. It is found that with an increase in the initial temperature of the specimen the initiation of shear bands is delayed, and wider bands form. © 1992.
