The deformation behaviour of structures under cyclic loading condition is simulated by using FE analysis in which a cyclic plasticity model, so-called a subloading surface model, is incorporated. The adopted cyclic plasticity model is categorized in the framework of unconventional plasticity models premising that the interior of the yield surface is not a purely elastic domain. In this study, several examples of FEM analysis on the cyclic deformation behaviour are presented to show the potential of the developed FEM program and the incorporated cyclic plasticity model.
