Abstract
Motivated by experimental findings on sheet-metal forming, this
article concerns the modeling of evolving anisotropies in finite
plasticity. A covariant formulation of plasticity is employed in conjunction
with evolution equations for the structural tensors that characterize the
symmetry group of the yield function. A specific model is implemented
into a finite element code to simulate tension and torsion tests.
The results are then compared to experiments.
