Strain-path change tests were performed on 5754-O aluminum alloy sheet sample by using equibiaxial stretch followed by uniaxial tension. A self-consistent viscoplastic polycrystal model was used to simulate the material response under non-linear strain paths and fit the experimental data. Recovery that occurred during the first and second loading steps was also assessed. Anisotropic strain hardening behaviors were incorporated in the model, which accounted for the transient behaviors upon the strain path change.
