Abstract

This paper deals with the two-dimensional rolling-sliding contact problem with frictional heat generation on an elastic half space containing a surface breaking crack. Rolling-sliding contact is simulated as an arbitraly distributed contact load with normal and shear components, moving with constant velocity over the surface of the half space. The frictional heat generation on the contact region is estimated by using of sliding velocity, frictional coefficient and contact pressure. Numerical results are given for the cases of Hertzian and parabolic distributed loading respectively. The effects of slide roll ratio and frictional coefficient on the stress intensity factors are considered.
