Prediction of Uniaxial and Biaxial Ratcheting by the Chaboche Model With Evolution for 304 Stainless Steel

The precision requirements for cyclic plasticity models are often not very high in industrial applications, even though the integrity of many components subjected to cyclic plasticity is critical.Despite its limitations, such as poor prediction of ratcheting behaviour, the Chaboche model remains the most widely used model of cyclic plasticity.This paper presents the calibration of this model for uniaxial and multiaxial cyclic data on 304 stainless steel.The model incorporates a strain memory surface dependence to account for pronounced cyclic hardening.Resulting simulations carried out by calibrated model are used to highlight some of the modelling limitations.
