This paper deals with the two-dimensional rolling-sliding contact problem with frictional heat generation on an elastic half-space containing multiple surface cracks. Rolling-sliding contact is simulated as an arbitrarily distributed contact load with normal and shear components, moving with constant velocity over the surface of the half-space. The frictional heat generation at the region of contact is estimated by use of sliding velocity, frictional coefficient and contact pressure. Numerical results of stress intensity factors are obtained for the case of a set of parallel cracks due to Hertzian- and parabolic-distributed loads. The interferential effects on the stress intensity factors with the distance between two cracks, as well as the effects of the slide/roll ratio, frictional coefficient and crack angle, are considered.
