In the present article, a displacement-based polynomial-type quasi-three-dimensional plate theory is developed and applied to predict the accurate thermomechanical bending behavior of sandwich plates with functionally graded (FG) skins and a homogenous isotropic core. The theory considers the effects of transverse shear and normal stresses. The -directional and -directional displacements consist of extension, bending, and shear components expanded up to fifth-order polynomials in terms of the thickness coordinates. The -directional displacement consists of a transverse normal effect up to a fourth-order polynomial in terms of the thickness coordinate. The governing equations are extracted using the principle of virtual work, and thermomechanical bending solution for simply supported plates is obtained using Navier’s solution technique. The present results are compared with the previously published results and are found to be in good agreement with them.
