AXISYMMETRICAL TRANSIENT CONTACT PROBLEM FOR SLIDING BODIES WITH HEAT-GENERATION

A transient contact problem with frictional heating for two sliding half-spaces is considered. One of the two half-spaces is assumed to be slightly curved to give a Hertzian initial pressure distribution; the other is a rigid non-conductor. The problem is formulated in terms of one integral equation with unknown heat flux at the interface. The equation is solved numerically, using appropriately chosen Green's functions. Contact pressure and temperatures are found for various values of an independent parameter-the ratio of initial width of contact to the width in the steady state.
