Bending of exponentially graded plates integrated with piezoelectric fiber-reinforced composite actuators resting on elastic foundations

This paper introduces analytical solution for exponentially graded (EG) plates attached with a single-layer of piezoelectric fiber reinforced composite (PFRC) actuator. The plate is undergoing sinusoidal electromechanical loads and resting on Pasternak-Winkler's elastic foundations. The displacement components are expressed via a higher-order shear deformation theory. The distributions of the electric potential are vary linearly along the thickness direction. The equations of equilibrium and boundary conditions are established by applying the principle of virtual displacements. Navier's method is used to obtain the problem solution. The influences of various parameters like voltage amount, side-to-thickness ratio, Young's modulus ratio and elastic foundations parameters are investigated. The current formulations are validated by comparison with published results.
