This study deals with the thermoelectroelastic behaviors of a fluid-filled functionally graded piezoelectric material (FGPM) cylindrical thin-shell under the combination of mechanical, thermal and electrical loads. The FGPM is composed of piezo ceramic and metal components and the holistic material properties are assumed to vary continuously through the thickness of the shell with power law. Based on the classical cylindrical shell theory, the governing differential equations are derived. Applying the analytical method, exact solution of the problem is obtained. Finally, through numerical examples, the influences of various factors on the thermoelectroelastic behaviors of the fluid-filled FGPM cylindrical thin-shell have been analyzed and discussed.
