Simulation of the rolling texture of pure Al using crystal plasticity finite element method

The Taylor-type and finite element polycrystal model were incorporated into the commercial finite element code ABAQUS on the basis of the crystal plasticity theory of rate-dependent polycrystal constitutive relations. Initial orientations obtained by electron backscatter diffraction (EBSD) were directly input into the crystal plasticity finite element model (CPFEM) to simulate the rolling texture of fcc 1050 pure Al at two stains. Comparisons of simulated and experimental results showed that texture predictions of cold rolling by the finite element model were more approximate to the experiment result. The Taylor-type model predicted that orientations accumulated in the {4411} <11118> orientation which would be called Dillamore orientation. The finite element model predicted the copper orientation that was more approximate to the experiment result than Taylortype model. No {011} <211> brass orientation, {123} <523> S orientation, {011} <100> Goss orientation and other ideal orientations were simulated.
