A new damage-mechanics-based model for rolling contact

Apr 01, 2018· This study aims to develop a damage-mechanics-based approach for subsurface-originated RCF of the outer ring of a cylindrical roller bearing. First, a two-dimensional explicit FE model is built in ABAQUS to calculate the cyclic rolling contact stresses. In the model, the roller is set to repeatedly roll across the surface of the outer ring.
