"Plasticity models included in commercial FEM software are not able to describe well such cyclic plasticity effects as multiaxial ratcheting or cyclic hardening caused by nonproportional loading. This problem is presented in the contribution on an example of experimental data of 316L steel which embodies the mentioned behavior of some steels. For this numerical study the experimental data published by Portier et al. [Int. J. Plasticity 16 (2000) 303] were adopted. There are tested the kinematic hardening rules proposed by Besseling, Chaboche and AbdelKarim- Ohno in the contribution. For the proposed modification of AbdelKarim-Ohno model the markedly better agreement with experiments is achieved. The way of implementation into a FE code of the proposed material model is described at the end of the contribution."@en . . "6"^^ . "2"^^ . . "Z(MSM6198910027)" .
