Comparison of the deformation and incremental theory of plasticity used for experimental mechanics problems
D. Vavřík
pages 1387 - 1391, full text

Deformation Theory of Plasticity is often used for evaluation of the experimental data. 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 It will be shown in this paper that this presupposition can be no longer valid if high ductile material is used although external loading is strictly monotonic and proportional.
