Abstract
his study fulfils a thermo-hygro-mechanical analysis of the bending behavior of FG plates resting
on different elastic foundation models. A quasi-3D high-order shear deformation theory with five unknowns
is used herein to perform this analysis. The impact of shear deformation and stretching effect are included in
the formulation of the used approach. The result of the change in material characteristics and the volumetric
fraction of components on the bending response of FG plates in a thermo-hygro-mechanical environment is
analyzed and discussed. The principle of virtual displacements is used to obtain the equilibrium equations,
and the Navier-type solution is applied to solve the resulting equations. The results show that the increase in
thermal load and moisture concentration causes a rapid deflection increase. Furthermore, the Winkler parameter
influences the shear stresses more than the deflections.
