Effect of heat-conductive filler of interface gap on thermoelastic contact of solids

Thermoelastic Interaction of the Bodies with Regular Surface Textures in the Presence of Heat-Permeable Media in the Intercontact Gaps

“…7). As in the case of thermoelastic contact of the bodies in the presence of a local interface gap caused by a groove on the surface of one of the bodies [9,32], the influence of thermal conductivity of the filler of the gap on the distribution of contact pressure is negligible (Fig. 8).…”

“…which takes into account conditions (10) and (11) imposed at infinity [4,5,9,32] For the formulated periodic contact problem, the complex potentials F(z) , Φ 1 (z) , and Φ 2 (z) take the form…”

“…For the solution of the system of equations (19), (20), we apply the analytic-numerical technique developed in [32] and based on the method of successive approximations and the analytic-numerical approach [5] to the solution of the Prandtl singular integrodifferential equation in the class of functions equal to zero together with their first derivatives at the endpoints of the interval of integration.…”

“…Earlier, the thermoelastic interaction of two half spaces was studied in the cases where the intercontact gaps are filled with heat-permeable media and caused either by local grooves [5,32] or by the delamination in the region with surface thermal resistance [4]. In what follows, we investigate the thermoelastic contact of two semiinfinite bodies one of which has a regular surface texture with regard for the fact that intercontact gaps are filled with heat-permeable media.…”

“…Every gap contains a heat-permeable medium (gas or liquid) with the same thermal conductivity coefficient λ . We model its influence on the process of contact heat exchange by the thermal resistance [5,32]:…”
