Mutual Interference of Two Subsurface Cracks in a Semi-Infinite Body Due to Rolling Contact with Frictional Heating

摘要

This paper deals with the two-dimensional thermoelastic contact problem of a rolling rigid roller of specified shape, which induced of friction and heat generation in the contact region, moving with constant velocity in an elastic half-space containing a couple of subsurface cracks. In the present temperature analysis, the speed of the moving heat source is assumed to be much greater than the ratio of the thermal diffusivity and the half contact length.
