| Abstract |
The development of deformation texture in FCC polycrystalline metals during plane strain compression and simple shear was simulated by the finite element analysis using a large-deformation, elastic-plastic, rate-dependent polycrystalline model of crystal plasticity. The results obtained were compared with those calculated from full-constraint, rate-dependent polycrystalline model. The calculated texture from the FEM showed the same main component with a little different intensity from that simulated by the full constraint model. The simulation of plane strain compression with a high rate sensitivity resulted in weaker preferred orientations in the texture and change in the main component from Dillamore to Brass component. |
