Abstract
This paper presents a theoretical investigation on the response of the thermo-mechanical bending of FG plate on
variable elastic foundation. A quasi-3D higher shear deformation theory is used that contains undetermined integral forms and
involves only four unknowns to derive. The FG plates are supposed simply supported with temperature-dependent material
properties and subjected to nonlinear temperature rise. Various homogenization models are used to estimate the effective
material properties such as temperature-dependent thermoelastic properties. Equations of motion are derived from the principle
of virtual displacements and Navier’s solution is used to solve the problem of simply supported plates. Numerical results for
deflections and stresses of FG plate with temperature-dependent material properties are investigated. It can be concluded that the
proposed theory is accurate and simple in solving the thermoelastic bending behavior of FG thick plates.
