Unsteady thermal stresses in a functionally gradient material plate were discussed. Firstly, a one-dimensional unsteady heat transfer problem for heterogeneous materials was analyzed with the newly proposed method using the proper transformation of variable, the Laplace transformation and the perturbation method. The one-cycle temperature boundary condition was asumed ; both surfaces of the plate were heated from the initial state of room temperature, and after the steady state was reached, both surfaces were cooled until the initial state was attained. During the cooling process, large tensile stresses appeared on the ceramic surface at the earlier stage, but the damage region was restricted to the thin layer on the surface. The influence of the mechanical boundary conditions was also discussed.
