[en] This paper presents the simulation of a deep-drawing process using three different constitutive laws: strain rate space yield locus description with an isotropic hardening law, strain rate space yield locus description with a combined (isotropic and kinematic) hardening law, and stress space yield locus description with an isotropic hardening law. To take into consideration material anisotropy, the yield locus is computed from the crystallographic texture using Taylor's model, a dual plastic potantial and combined hardening law taking into account the dislocations microstructures. The results obtained by these three constitutive laws are compared with experimental ones.
