摘要：

Modeling the plastic behaviour of 3104 aluminium alloy in the H19 condition was undertaken by introducing a kinematic hardening to account for strong effects of strain-path changes. The identification of the model involved a number of non-standard tests such as simple shear, either monotonic or cyclic, and simple shear/tension sequences. The material is well described considering a strong kinematic hardening superimposed on a saturating isotropic hardening. The model accounts for the softening effect observed on tensile specimens in the hoop direction of a deep-drawn cup.
