Three-dimensional piezothermoelastic solution for shape control of cylindrical panel

Abstract

A three-dimensional exact solution is presented for a simply supported, cross-ply laminated finite cylindrical panel with some piezoelectric layers subjected to thermoelectromechanical load. The variables are expanded in Fourier series to satisfy the boundary conditions at the ends. The solution is constructed as a product of an exponential function and a power series. The field equations yield characteristic equations for the exponents and recursive relations for the coefficients of the power series. Results are presented for thermoelectrical load to illustrate the effect of the thickness parameter. The feasibility of reducing deflection and stresses due to thermal load by actuating a piezoelectric layer is reported The effectiveness of various actuating schemes for shape control of thermally loaded panel is investigated.
