Boundary element analysis for thermomechanical interface stress in the thin-layered media under sliding contact

摘要

The present work examines the influence of a surface coating on the temperature distribution and the thermomechanical stress Held produced by friction in a sliding contact. A two-dimensional transient model of a layered medium moving with constant velocity relative to a heat source is presented. A solution technique based on the boundary element method employing the multiregion technique is utilized. Results are presented showing the influence of coating thickness, thermal properties, Peclet number, and mechanical properties. It shows that the mechanical properties and thickness of coating have a significant influence on the stress field. The effect of the ratio of shear modules is more important than the effects of the ratios of other mechanical properties.
