Description of Texture and Yield Locus Evolution Under Different Deformation Paths of Copper Sheet

Received13 Mar 1995

Abstract

The evolution of texture with plastic deformation along different loading paths has been studied for a commercial DHP copper sheet metal. Two models have been utilized to predict the evolution of textures: Viscoplastic under Relaxed Constraints conditions (VRC) and a Self Consistent approach (SC) with viscoplastic conditions, where the {111}<110> active slip systems were selected according to a strain rate sensitivity law.The stress-strain curves along different loading paths were calculated taking into account the texture evolution predicted by VRC and SC models. Predictions with the SC formulation were very close to experimental results. Texture evolution depended on the deformation path.
