To study the thermoelastic behavior of coatings a two-dimensional model of a finite thickness layered medium submitted to a moving heat flux was presented in a previous paper (Leroy, Floquet, and Villechaise, 1989). The influence of thin coatings with variable properties or thicknesses on the temperature and stress fields is studied here. These results show that important stresses occur in a coating whose properties differ from those of the substrate, even for low temperature rises.
