The influence of ring crack location within the contact path on rolling contact fatigue failure has been studied using numerical fracture analysis. The numerical calculations are based on a three-dimensional model for the ring crack propagation. The ring crack is considered as a conic shape with a curved line as the crack front. The rolling contact loading is simulated by repeated Hertzian point contact load with normal pressure and tangential traction. Fracture mechanics analysis is utilised to determine the stress intensity factors (SIFs) along the crack front and the SIFs are analysed using a three-dimensional boundary element model. The analytical results are verified by experimental studies, which show that present predictions of ring crack location influence are consistent with the experimental observations
