Numerical study of large strain behavior of OFHC copper: The role of latent hardening

Two mean-field crystal plasticity models of the Taylor model and the Affine model have been employed to study the large strain behaviors of OFHC copper under uniaxial compression, uniaxial tension, plane strain compression, simple shear and fixed-end thin-walled tubular torsion. The effect of latent-hardening on the predictability of the models is assessed through comparing the simulated results with the corresponding experiments. Both the …
