In order to describe cyclic plasticity phenomena the plastic stretching within a yield surface has to be considered. Subloading surface model categorized in the unconventional plasticity models and describing a smooth elastic-plastic transition would be applicable to non-proportional loading process including cyclic loading behavior of materials with a smooth yield surface. In this study the model is extended for materials exhibiting a purely elastic response under a particular state of stress state, named an elastic boundary surface, whilst they also exhibit a smooth elastic-plastic transition. A damage evolution is also described by incorporating a damage function for the conventional model. The applicability of the model to the cyclic plasticity phenomena observed for the cyclic stresses below the yield stress is verified through the comparison with the experimental data.
