Prediction of deformation texture evolution in FCC polycrystalline metals using finite element method of crystal plasticity

摘要

The development of deformation texture in FCCpolycystalline metals during plane strain compression andsimple shear was simulated by the finite element analysis using alarge-deformation, elastic-plastic, rate-dependent polycrystallinemodel of crystal plasticity. The results obtained were comparedwith those calculated from full-constraint, rate-dependentpolycrystalline model. The calculated texture from the FEMshowed the same main component with a little different intensityfrom that simulated by the full constraint model. The simulation ofplane strain compression with a high rate sensitivity resulted inweaker preferred orientations in the texture and change in the maincomponent from Dillamore to Brass component.
