[Abstract] In this paper, stress strain deformation behaviors of 780 MPa grade high tensile strength steel sheet (HTSS) after biaxial tension tests were investigated. To evaluate the accuracy of our constitutive model which can describe cyclic deformation behaviors of HTSS, several experimental results with stress path change were compared with the corresponding calculated results by using both an isotropic hardening model (IH model) and our kinematic hardening model (Yoshida-Uemori model). It is found that experimental stress strain curve after biaxial deformation show the lower flow stress than uniaxial tension flow stress. Our Yoshida-Uemori model can describe the above mentioned stress strain behavior however the IH model can not represent with accuracy. Yoshida-Uemori model provides a very good description of the stress strain behaviors after pre biaxial deformation histories.
