Main reason of this theory using is its simple implementation into experimental-numeric software. It is supposed that difference between power low and appropriate incremental theory applied is negligible if monotonic loading is presented and isotropic material is used. It is shown in this paper that this presupposition can be no longer valid if high ductile material is used although external loading is strictly monotonic and proportional.
