Simulation of rolling deformation texture of fcc metals with crystal plasticity finite element model

Abstract

A rate dependent crystal plasticity constitutive model with respect to self-hardening and latent hardening in finite element (FE) analysis is developed to simulate rolling texture in the present paper. The influence of grain interaction is modelled by different assignment of orientations to FEs. The simulation results reveal that the grain interaction will lead to mesoscale inhomogeneous deformation and that grains rotate faster in the extended Taylor type crystal plasticity finite element (CPFE) model without consideration of grain interaction than in the full CPFE model with grain interaction. The rotation of grain boundary is slowed down owing to the grain interaction. Assigning more elements to one grain, in which both the boundary and interior of grain are simulated, better simulation results can be obtained.
