“…It is known that the integration and collocation points in this study can not be arbitrarily selected. This becomes an apparent deficiency when solving a small kinked branch problem (Mukai 2000). However this weakness can be alleviated by increasing the number of the integration points.…”

Cracking of a fluid-filled subsurface crack is studied by means of the distributed dislocation technique within the framework of twodimensional linear elastic fracture mechanics. The Griffith crack was initially opened by the application of hydrostatic pressure of an incompressible fluid within the crack. A moving Hertz line contact load distribution is applied at the surface of the half-plane in the presence of friction. The stress intensity factors at the tips of the fluid-filled crack are analyzed with the restriction that due to the fluid incompressibility there is no change of the crack-opening volume. When the crack starts to propagate/kink, numerical results show that the internal fluid pressure will be relieved, and as the ratio of the branched crack length to main crack length increases, the elastic strain energy release rate decreases. The crack growth is assumed to be arrested when the energy release rate is below a certain value. Based on the energy criterion, predictions are attempted for determining the load position where the crack propagation/kink commences as well as the growth increment of the branch crack before it is arrested. A step-by-step crack path is constructed to simulate the growth pattern of the fluid-filled crack under moving Hertzian loading.

“…However, the actual crack is apt to branch and is propagated into a pitting or shelling failure. As to the analysis for branched crack due to the rolling contact, Farris et al (9) , Yu et al (10) and Mukai et al (11) have studied the kinked direction from subsurface crack. However, they do not consider the crack growth path until the failure and their fatigue life due to the rolling-sliding contact.…”

At first, we analyze the stress intensity factors at a crack tip of multiple kinked crack from a horizontal initial crack in a half-space due to rolling/sliding contact with frictional heat. On the basis of the results of stress intensity factors and applying the maximum energy release rate criterion to each kinks in order, the two-dimensional fatigue crack growth path are simulated, and making use of the fatigue crack growth law obtained from fatigue experimental results for a high carbon chromium bearing steel (AISI-52100), the propagation fatigue lives until the surface tribological failures are predicted due to the repetition of rolling-sliding contact. And we show that the increase of frictional coefficient, sliding/rolling ratio reduce the propagation fatigue lives, and the shortening of the depth of a horizontal initial subsurface crack reduce the propagation life and is apt to be easily induced the fatigue surface tribological failures.
