The paper describes the role of different terms in asymptotic expansion of the stress field around surface crack tip under lubricated contact conditions. The maximum tangential stress (MTS) crack propagation criterion is modified to account for the influence of internal pressure along the crack surfaces due to trapped fluid. The developed model is used to simulate surface crack growth on a gear tooth flank. Comparison with experimental results shows that the modified MTS criterion predicts the kink angle more accurately than the original criterion.
