An anisotropic yield function accounting for both the Bauschinger effect and the cross effect is developed in this report. Based on the representation theorem for isotropic tensors, a new yield function, as an extension of the Baltov-Sawczuk theory, is presented. After a short discussion on the anisotropic parameters in the model, the experimental verification is carried out for SUS304 stainless steel at room and elevated temperature levels in a biaxial stress state of tension and torsion. The calculated results show good agreement with the experimental data, especially when prediction the distortion and the translation of the yield surface during the inelastic deformation processes.
