This paper is concerned with the theoretical treatment of transient piezothermoelastic problem involving a functionally graded thermopiezoelec-tric cylindrical panel due to nonuniform heat supply in the circumferential direction. The thermal, thermoelastic and piezoelectric constants of the cylindrical panel are expressed as power functions of the radial coordinate variable. We obtained the exact solution for the two-dimensional temperature change in a transient state, and piezothermoelastic response of a simply supported cylindrical panel under the state of plane strain. Some numerical results are shown in figures. Furthermore, the influence of the nonhomogeneity of the material is investigated
