“…The previous studies (Way 1935;Keer and Bryant 1983;Kaneta et al 1985;Bower 1988;Kudish 1995;Chue and Chung 2000;Datsyshyn et al , 2004Datsyshyn and Levus 2003;Kudish and Burris 2004;Zafošnik et al 2004;Bogdañski et al 2005) largely dealing with edge cracks have found their applications in tribology when modeling the surface pitting mechanisms. In a series of studies, Datsyshyn and her coworkers (Datsyshyn et al , 2004Datsyshyn and Levus 2003) have investigated the trajectories of propagation of an edge crack under the conditions of boundary lubrication. They were able to construct the step-by-step crack path based on their curvilinear crack analysis.…”

“…The results of their analysis were applied to model the bone-implant interface. It will be evident later that our current analysis incorporates certain features of the above modeling (Kudish 1995;Datsyshyn et al , 2004Datsyshyn and Levus 2003;Kudish and Burris 2004;Santare et al 1987). The presence of fluid in a subsurface crack can be accomplished by either injection or entrapment and sealed by adhesive or a stress field.…”

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.
