Constitutive Modeling of Cyclic Plastic Behaviour of 304 Stainless Steel Under Temperature Variation

Summary:The constitutive model based on the cyclic nonhardening region is applied first to describing the cyclic plastic behaviour of 304 stainless steel under in-phase and out-of-phase cyclic changes of temperature and athermal strain ; temperature is cycled between 200°C and 550°C. Fairly good agreement between the predictions and the experiments is obtained, if we assume that the internal change proper to the higher temperature (i.e., 500 or 550°C) is induced predominantly under such nonisothermal cyclic loading. On the basis of this finding, then, the evolution equation of isotropic hardening is extended so that it can be valid even for irregular variations of temperature. The validity of the extended model is ascertained by comparing its predictions with the experiments on 304 stainless steel performed recently by Niitsu and Ikegami.
