Abstract
Two modifications of AbdelKarim-Ohno [Int. J. Plasticity 16 (2000) 225] cyclic plasticity
model were proposed for better ratcheting simulations [Trans. VŠB-TUO Mech. Ser. (2006) 155].
The developed model was implemented into commercial FE software Ansys. In this paper, the model
was verified on a set of axial/torsional loading paths taken from Chen et al. [Int. J. Plasticity 21
(2005) 161]. The model predicts ratcheting strain reasonably well for the almost all test cases.
