The proposed linearized yield function considers the crystal lattice constants and the parameters of crystallographic orientation of material and has simplified form, which makes it suitable for technological calculations of sheet metal forming processes. It is shown that the Lode coefficient is determined not only by the stress state, as in the case of an isotropic material, but also depends on anisotropy parameters, which reflects the elastic constants of the crystal lattice and the crystallographic orientation of the structure.
