چکیده مقاله
One of the phenomena in cyclic plasticity that plays an important role in models of materials when they are subjected to cyclic loading is ratcheting Ratcheting is defined as a strain accumulation under stress controlled cycling with non zero mean stress Ratcheting depends on loading conditions and loading history In this study, cyclic bending behaviors of sheet are investigated under different types of loading conditions The kinematic hardening theory based on the Chaboche model is used to predict the plastic behavior of the structures An iterative method is developed to analyze the structural behavior under cyclic loading conditions based on the Chaboche kinematic hardening model with three decomposed components
