Abstract
In this work, the bending behavior of functionally graded (FG) porous plates connected with a layer made of piezoelectric fiber-reinforced composite (PFRC) on the upper surface is presented via a quasi-three dimensional (3D) refined shear and normal deformation theory. The shear strains and normal deformation are both studied and so, the shear correction operator is not needed. The plate is under sinusoidal electro-mechanical loads. The material characteristics of the FG porous plate have continuous variation in the direction of thickness relying on a modified exponential function. The equilibrium equations will be established by utilizing the principle of virtual work and will be solved by considering Navier’s solution method. The electric potential effects on the present analyses are studied. The influence of porosity coefficient, inhomogeneity parameter, applied voltage, length-to-thickness ratio, and length-to-width ratio parameters will be discussed. By comparing it with other published studies, the efficiency of the current theory is verified.
