The present study predicts ratcheting response of 304, 1045 and 1Cr18Ni9Ti steel alloys using kinematic hardening rules of Ohno-Wang (O-W), Chen-Jiao-Kim (C-J-K) and newly modified hardening rule introduced by the present authors under various multiaxial loading histories. The predicted ratcheting curves based on these hardening rules were discussed based on their framework and parameters as compared with experimental data under various loading paths.
