Abstract

Simulating plane strain compression of polycrystalline 3004 aluminum, representing a metal of high stacking fault energy (sfe), to 60% reduction by a finite element model permits prediction of the observed texture, in which the copper, S, and brass components co-exist (predicted by neither the Taylor nor the Sachs models). Modeling the rate of hardening on individual slip planes and latent hardening introduces additional shear strains and increases the volume fraction of the brass component, showing how the brass texture may develop in metals of high sfe, in the absence of twinning and shear banding as suggested by Leffers and Pedersen and by Engler.
