Description:

Plasticity models, included in the most popular commercial FEM software, are not able to describe well such cyclic plasticity effects as multiaxial ratcheting or cyclic hardening caused by nonproportional loading. For example in the case of stainless steels it is necessary to use a robust cyclic plasticity model. This paper shows some iinteresting results from FE simulations of stress-strain behaviour of stainless steel 316L using new cyclic plasticity model with superposition of the kinematic hardening rule of AbdelKarim and Ohno [11] and the isotropic hardening rule of Calloch and Marquis [14]. On the basis of performed simulations, a fatigue study has been performed which shows the influence of material option in a FE computation on accuracy of life prediction. The conclusion presents recommendations for the calibration of cyclic plasticity models of Chaboche type. and Obsahuje seznam literatury
