Simulation of Flow Behavior and Texture Evolution of Cu-Ag composites incorporating XRD data

Abstract

This paper investigates the effect of cold drawing operations on the evolution of microstructure and texture in Cu-Ag composites. We use a crystal plasticity model to capture the flow behavior and texture of two different cold drawn composites. The three-dimension finite element simulations are able to capture the formation of Cu/Ag lamellar and grain structure inside the representative volume element (RVE). Stress-strain curves from compression tests and the measured texture after compression are presented. The numerical model is validated by experimental compression tests for a constant strain rate 10^-2 s^-1 at room temperature. The numerical simulations show the good capabilities of the model in reproducing the measurements.
