International Journal of PlasticityRésumé
In the work presented in this paper, several strain rate potentials are examined in order to analyze their ability to model the initial stress and strain anisotropy of several orthotropic sheet materials. Classical quadratic and more advanced non-quadratic strain rate potentials are investigated in the case of FCC and BCC polycrystals. Different identifications procedures are proposed, which are taking into account the crystallographic texture and/or a set of mechanical test data in the determination of the material parameters.

Article dans une revue avec comité de lectureRABAHALLAH, Meziane; BOUVIER, Salima; BALAN, Tudor; BACROIX, Brigitte (Elsevier, 2009)For numerical simulation of sheet metal forming, more and more advanced phenomenological functions are used to model the anisotropic yielding. The latter can be described by an adjustment of the coefficients of the yield ...

The latter approach ...
