Quantitative analysis of upset texture by crystal plasticity: finite element analysis

Abstract

The effect of friction and strain state in upset deformation on deformed texture was investigated by crystal plasticity finite element method. It was observed that around 60% among random initial texture evolves to < 111 > within 10 degrees of the upset axis(ND) by 80% upset near the quasi-uniaxial regions, while smearing of this texture components was predicted near the shear dominant regions. Texture intensity plot was introduced to quantitatively investigate the distributions of deformed textures. In addition, a simple Schmid analysis was also performed to explain the origin of strong ND parallel to < 111 > and ND parallel to < 100 > textures from randomly distributed grains.
