Elastic-Plastic Finite Element Stress Analysis of Two-Dimensional Rolling Contact


Cyclic plastic deformation is a major cause of failure in rolling elements. Previous work reveals that a cyclic plasticity theory plays a critical role in the elastic-plastic stress analysis of rolling contact. In this paper, a recently developed cyclic plasticity model is integrated into a commercially available finite element package. The plasticity model is characterized by its ability to describe general cyclic stress-strain phenomena that occur in rolling contact. The finite element model with the implementation of the plasticity theory is used to simulate the elastic-plastic stresses for line rolling contact. The normal contact pressure is idealized as the Hertzian distribution and the tangential force is assumed to be proportional to the normal pressure. Detailed stress and strain histories as well as residual stresses and plastic flow are obtained for repeated rolling. It is found that the residual stresses stabilize after a limited number of rolling passes but the plastic flow persists. The rate of plastic flow decreases with increasing number of rolling passes.
