初始屈服点处的力学性能并不能完全反映材料在变形过程中表现出的全部变形特

The mechanical properties at the initial yield point cannot fully reflect all the deformation characteristics of the material during the deformation process; the mechanical properties required to calibrate the yield criterion are expressed as a function of EPS, which can continuously capture the anisotropic evolution and plasticity of the yield surface The change of the potential surface provides an accurate description of the anisotropic behavior under different plastic strain levels.
