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

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° 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||<111> and ND||<100> textures from randomly distributed grains.
