Abstract
This 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 Naviertype 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
