Laminated composite materials are widely used in many industries like aerospace and nuclear industries because of their properties such as flexibility in designing and high stiffness to weight ratio. On the other hand, the use of piezoelectric effect in smart structures, has interested the researchers to enhance the accuracy and the effectiveness of the analytical methods used to predict the behavior of piezoelectric composite plates. In the present study, static, mechanical and electrical buckling and free vibration analysis of laminated composite plates with two piezoelectric layers on top and bottom of the plate for different mechanical and electrical boundry conditions are presented. These plates are analysed based on refined plate theory in which the displacement field is divided into bending and shear parts and shear displacements are modeled properly without using a shear correction factor. In this study principle of virtual work is employed to obtain finite strip solution. Finally, the results obtained from the proposed method has been verified using the results from other studies.
