Micro Abstract:
Motivated by the experimental findings on sheet metal presented in (J. Mech. Phys. Solids 45, 22, 841--851, 1997) we focus on the elaboration of a specific model which allows us to capture the evolution of the plastic anisotropy that is induced by finite strain plastic deformations. We discuss evolution equations for the structural tensor that characterises the material symmetry group and show that the finite element based simulation results are in good agreement with experimental findings.
