Effects of the isotropic and anisotropic hardening within each grain on the evolution of the flow stress, the r-value and the deformation texture of tensile tests for AA6016 sheets KU Leuven
Both the isotropic and anisotropic hardening laws implemented in a crystal elastic visco-plastic finite element model (CEPFEM) were tested for the prediction of the flow stress, the r-value and the deformation texture for tensile tests of the AA6016 sheet. The isotropic hardening law provides good predictions of the flow stress anisotropy. The dislocation hardening was found to be dominant in the hardening behavior. By accounting for the ...
