 note = {A numerical study is made of the dynamic thermal stresses in a ceramic metal Functionally Graded Material (FGM) subjected to impulsive electromagnetic radiation. The radiation absorption is assumed to maintain a constant energy flux throughout the pulse duration, and to diminish exponentially with depth. Since the wave travel time is small compared with the time necessary to reach thermal equilibrium. the thermal diffusion term is ignored in the transient heat conduction equation. In treating problems, the material properties of FGM are assumed to be temperaturedependent. In this paper, a set of unified equations is presented, which is applicable to the propagation of plane, cylindrical and spherical waves in clastic media. The characteristic equations are then derived and the numerical procedures involving stepwise integration along the characteristics are established. Numerical calculations are carried out for various FGM plates, and the significance of the temperature-dependent material properties and the effects of composition distribution of the FGM on the magnitude of the dynamic thermal stresses are discussed.},
