Finite element (FE) method has been widely used in industries for evaluation of material performance and for product design. Since most sheet metals exhibit noticeable plastic anisotropy, the use of an appropriate anisotropic plasticity model is important in order to predict accurately and efficiently the anisotropic deformation behavior, such as the undulations of cup height (i.e., earing behavior) in a deep drawing operation and the non-unity Lankford parameter (i.e., r-value) in a uniaxial tensile test.In the literature, various phenomenological yield criteria have been proposed to account for the plastic anisotropy (see the survey of Bacroix et al.
