Levy-type piezothermoelastic solution for hybrid plate by using first-order shear deformation theory

A Levy-type solution is presented for hybrid rectangular plates, with two opposite edges simply supported, made of a cross-ply composite laminate with attached piezoelectric layers, and subjected to thermoelectromechanical load. First-order shear deformation and classical lamination theories are used. A mixed formulation is employed for the solution. The effect of the width-to-depth ratio and aspect ratio on deflection and force resultants has been illustrated for a uniform load on plates with various boundary conditions. The effect of shear deformation on deflection and force resultants for moderately thick plates is generally more pronounced for the mechanical load case than for the self-straining cases of thermal and electric loads.
