Multi-scale numerical modeling of the multi-pass rolling texture evolution by using crystal plasticity and finite element method

Abstract. The finite element method (FEM) combined with the crystal plasticity (CP) model was used to predict crystallographic texture evolution during multi-pass asymmetric rolling of the polycrystalline aluminum with tilted entry into the rolling gap. The FEM macro-scale model of the rolling process with various asymmetry was performed using Abaqus commercial software. The asymmetry was introduced by difference in the diameters of cooperating rolls and various tilt angles of the rolled bar entry into the rolling gap. Predicted stress distribution over sample volume was used as the boundary conditions in the crystal plasticity meso-scale model of the plastic deformation. The CP meso-scale model developed by Leffers and Wierzbanowski [1], [2] was used as a post-processing procedure. The predicted evolution of the rolling texture distribution on the rolled bar thickness turned out to be in good agreement with that measured for specimens rolled with the same parameters as the ones used for modeling. Impact of the rolling parameters on the texture evolution was found.
