Thermal ratchetting of 316FR steel cylinders subjected to the axial movement of temperature distribution is analyzed by implementing in finite element analysis three kinds of models, i.e., the elastic-perfectly plastic model, the Armstrong-Frederick model, and the Ohno-Wang model. The latter two models are specified in two forms, i.e., the combined kinematic and isotropic hardening from verified in a previous work and the kinematic hardening form with isotropic hardening neglected. It is shown that the analysis depends greatly on the models employed while it is influenced relatively little by the neglect of isotropic hardening. It is also shown that the Ohno-Wang model, which can express the closure of stress-strain hysteresis loops, gives good simulation of the experiments.
