This paper presents an analytical solution for the static analysis of exponentially functionally graded (E–FGM) rectangular plates integrated with piezoelectric fiber-reinforced composite (PFRC) actuators under electromechanical loadings. The four-variable refined plate theory is applied to express the displacement components. The plate is under mechanical load, and the piezoelectric faces are subjected to an applied voltage. The electrostatic potential is assumed to be linear through the thickness of PFRC. The equations of equilibrium are established by applying the principle of virtual work principle. Comparison studies have been carried out to verify the accuracy of the present model. Furthermore, the effects of some parameters on displacements and stresses of the plates, including applied voltage, material anisotropy and side-to-thickness ratio, are discussed.
