Abstract :
[en] This paper proposes an experimental and numerical investigation of the quasi-static mechanical behavior of TA6V at room temperature. Different loading conditions ( tension, compression, plane strain ans simple shear) were applied on a 0.6 mm thick sheet in several in plane directions. Based on the experimental results, several identifications are performed to determinate the parameters involved in the CPB06 yield criterion and its extensions. The error/time computation ratio for the different identifications is next analysed to fix the choice of the yield criterion. The latter is finally associated with an isotropic hardening law on the one side and a formulation taking into account the evolution of the yield locus on the other side in order to describe the material. The ability of the proposed formulations to predict the TA6V response is studied int he case of a deep-drawing process.
