Three well-known ratchetting models for metals with different hardening rules were calibrated using uniaxial experimental data from Bower (1989) [J. Mech. Phys. Solids, 31, pp. 455–470], and implemented in the FE code ABAQUS (Hibbitt et al., 1997 [ABAQUS Version 5.7]) to predict ratchetting results for a tension-torsion specimen. The models were integrated numerically by the implicit Backward Euler rule, and the material parameters were calibrated via optimization for the uniaxial experimental data. The algorithmic tangent stiffnesses of the models were derived to obtain efficient FE implementations. The calculated results for an FE model of the tension-torsion specimen were compared to experimental results. The model proposed by Jiang and Sehitoglu (1995) [Wear, 191, pp. 35–44] showed the best agreement both for the uniaxial and the structural component case. [S0094-4289(00)00701-5]
