THREE-DIMENSIONAL ELASTICITY SOLUTION OF SINGLE LAYER PIEZOELECTRIC PANEL

This research presents a semi analytical solution of finitely long, simply supported, orthotropic, piezoelectric, radically polarized, shell panel under pressure and electrostatic excitation. The general solution of the governing partial differential equations is obtained by the method of separation of variables. The displacements and electric potential are expanded in appropriate trigonometric Fourier series in the circumferential and axial coordinate to satisfy the boundary conditions at the simply-supported circumferential and axial edges. The governing ordinary differential equations are solved by the Galerkin finite element method. In this procedure, the quadratic shape function is used in each element. Numerical examples are provided for typical external pressure on outer .I ll/face of a single layer piezoelectric panel.
