The classical thermoelastic theory is that the propagation speed of a heat wave is infinite and its wave spreads to an infinite region instantly. On the other hand, the generalized thermoelastic theory is that its speed is finite and the relaxation time is introduced into classical thermoelastic one. This paper deals with the two-dimensional thermal stress analysis in the functionally gradient material subjected to partial heating based on the generalized thermoelastic theory, that is, Lord-Shulman and Green-Lindsay theories. Multilayer approximation method is used. Laplace and Fourier transforms are carried out for time and space variables, respectively. The temperature, displacements and thermal stresses are obtained by use of state space approach.
