| Abstract | Modelling micropit formation under rolling contact fatigue (RCF) is a big challenge due to strong dependence on microstructure. A RCF damage model was developed based on combined crystal plasticity theory and cohesive zone to study the crack growth and micropit formation. The results showed the crack growth is driven by shear stress, but affected by crystal orientation. Cracks would rather propagate transgranularly in the shear stress-dominant region as the damage accumulates inside grains faster than at grain boundaries. They changes to intergranular beyond the stress-dominated region becasue there is no enough driving force. The modelling results agree well the experiment. |
