Three-dimensional piezo-thermo-mechanical analysis for a finite cylindrical composite panel composed of cross-ply and piezoelectric laminate

The exact three-dimensional piezo-thermo-mechanical solution for a finite cylindrical composite panel composed of cross-ply and piezoelectric laminate is presented in this article. The panel is simply supported at four end edges and is subjected to thermo-mechanical loadings on its top and bottom surfaces, respectively. The piezoelectric layers are polarized along radial direction as a sensor. The variables are expanded layerwise in Fourier series to satisfy the boundary conditions at the simply supported ends. As an example, a cross-ply laminated cylindrical panel made of alumina fiber reinforced aluminum composite, associated with a piezoelectric material of crystal class mm2 is calculated. Furthermore, some numerical results for the temperature change, the displacement, stresses, electric potential, and electric displacement distributions are shown in figures and briefly discussed.
