A macroscopic two-surface model is used to describe the complex anisotropic behavior of this material. The model accounts for plastic anisotropy as well as yielding asymmetry due to twinning. The primary deformation mechanisms, glide by dislocation motion and twinning, are treated separately. A comprehensive database is used for model identification, which includes specimens along the plate principal directions and off-axes specimens along diagonal orientations in principal planes. Flow stresses and strain anisotropy (R-value) coefficients are included in the identification procedure. The parameter optimization strategy is presented. It is shown that the model captures the anisotropic behavior of the material.
