Abstract: 

A theoretical solution of the mechanical behavior of thick piezoelectric cylinders subjected to dynamic pressures is presented in this paper. The five governing equations in terms of resultant forces and resultant moments with respect to basic displacement vector components, and are used. The First-order Shear Deformation Theory (FSDT) is employed to consider the effects of shear forces on the shell structure. The effects of transverse shear deformation and rotary inertia are included into the analysis. The formulation is based on the thick-shell equations. Navier-type solutions are obtained and used for simply supported circular cylindrical shells. Finally, the New mark family of methods is used to numerically time integration of the system of coupled second order ODEs. Results obtained with the present analysis are found to be in good agreement with those available in the literature. The results of this paper can serve as a reference for future study in the design of smart engineering structures.
