Flexural Analysis of Smart Structural Composite Laminates by Using a New Higher Order Theory

The present article involved the enrichment of a higher order shear deformation theory especially for composite laminates embedded with piezoelectric materials under electro-mechanical loading. The main aim of the present investigation is to propose the analytical formulations and solutions to examine the flexural behavior of the laminated composite plates embedded with piezoelectric fiber reinforced composite by using a higher order theory. The assumed two models M1 & M2 are developed separately with individual higher order theories. The principle of virtual work is used in order to obtain the boundary conditions and the governing equations of equilibrium. The Navier's technique is involved in order to obtain the solutions. The results are tabulated and analyzed for different aspect ratios, voltages for the study of variation of in plane and transverse displacements and also the normal stresses and transverse shear stresses.
