AXISYMMETRICAL TRANSIENT CONTACT PROBLEM FOR SLIDING BODIES WITH HEAT-GENERATION

A transient contact problem with frictional heating for two sliding ha lf-spaces is considered. One of the two half-spaces is assumed to be s lightly curved to give a Hertzian initial pressure distribution; the o ther is a rigid non-conductor. The problem is formulated in terms of o ne integral equation with unknown heat flux at the interface. The equa tion is solved numerically, using appropriately chosen Green's functio ns. 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.
