Abstract
In this study, a combination of Chaboche’s nonlinear kinematic hardening model and Lemaitre’s anisotropic continuum damage mechanics (CDM) model is used to predict ratcheting strain of different loading paths. The fictitious continuum domain is considered, and the consistent relations are developed between real and fictitious materials. The return mapping algorithm is developed to obtain the plastic strain of different loading paths. Non-proportional loading paths are simulated by the combined model. The ratcheting strain of the stress-strain controlled loading paths is obtained numerically and compared with the experimental results of the cyclic loading tests of Corona et al.
