Histories Of The Stress, Strain-rate, Temperature And Spin In Steady State Penetration Problems

Abstract

Given the values of the two components of the velocity, temperature, hydrostatic pressure and work-hardening parameter at a large number of discrete points in a bounded 2-D domain, an algorithm has been developed to compute the streamline that passes through a desired point in the domain, and the time histories of the stress, strain-rate, temperature and the spin at a material particle, starting from the instant it occupied the desired point. Results for a few target points situated near the axis of symmetry in the steady state penetration problem involving a viscoplastic target and a rigid cylindrical penetrator are presented. Two nose shapes, namely a hemispherical and blunt, are considered. © 1989.
