Abstract

When two conformal bodies are placed in contact, the pressure distribution is sensitive to comparatively small changes in surface profile. Thermoelastic deformations , though generally small, can therefore have a major effect on systems involving contact. Further interesting effects are introduced if the thermal boundary conditions at the interface are influenced by the mechanical contact conditions. The thermal and thermoelastic problems are then coupled through the boundary conditions and the conventional uniqueness and existence theorems for heat conduction and linear elasticity do not apply to this coupled problem. We shall see that this can lead to the steady-state solution being non-unique and/or unstable.
