Pressure vessels, turbines, spacecrafts, and many equipments in nuclear technology are subject to cycles of load and to cycles of temperature, both or separately. Therefore, many researchers, such as Drucker and Palgen [1], Chaboche and Rousselier [2], Eisenberg and Yen [3], and Mroz [4] have investigated cyclic plasticity of materials. Among many models proposed to fit one or more aspects of the response under cyclic loading, only few models can be used effectively in computer programs for complicated structural stress analysis, and at the same time meet the essential features of plastic behaviour of materials under cyclic loading.

In this paper the authors proposed the constitutive model for cyclic plasticity incorporating the motion of the center of the loading surface and the plastic deformation-induced-anisotropy. The Ramberg-Osgood law was applied to each cycle with respect to the current center of the loading surface. The computer simulation based on this model was verified by virtue of several kinds of experiments on type 304 austenitic stainless steel. As a result, this model was recognized to be adequate to describe the essential features of cyclic plasticity.
