This paper is concerned with the dynamic treatment of thermal stresses in an infinite plate of functionally graded material (FGM) subjected to uniform impulsive electromagnetic radiation. Heating is assumed to be a step function in time, and to diminish exponentially with the distance from the exposed surface of the plate, assuming negligible heat conduction. In treating problems, the nature of the stress-wave buildup in the absorption plate is studied for the case of a temperature-dependent solid, i.e. , when material properties vary with temperature. The numerical procedure employs the characteristic method based on the integration of the governing equations along the characteristics. Numerical examples are presented for several PSZ (partially stabilized zirconia)/SUS_<304> (type 304 stainless steel) FGM showing the significance of the dynamic effects and the temperature-dependent properties of material to the thermoelastic material design of FGM.
