Thermal distortion of an anisotropic elastic half-plane and its application in contact problems including frictional heating

Abstract

The thermal surface distortion of an anisotropic elastic half-plane is studied using the extended version of Stroh's formalism. In general, the curvature of the surface depends both on the local heat flux into the half-plane and the local temperature variation along the surface. However if the material is orthotropic, the curvature of the surface depends only on the local heat flux into the half-plane. As a direct application, the two-dimensional thermoelastic contact problem of an indenter sliding against an orthotropic half-plane is considered Two cases, where the indenter has either a flat or a parabolic profile, are studied in detail. Comparisons with other available results in the literature show that the present method is correct and accurate. Copyright © 2006 by ASME.
