Abstract
The aim of this work is to study the hygro-thermo-mechanical bending responses of simply supported FG plate
resting on a Winkler-Pasternak elastic foundation. The effect transverse shear strains is taken into account in which the zero
transverse shear stress condition on the top and bottom surfaces of the plate is ensured without using any shear correction
factors. The developed model contains only four unknowns variable which is reduced compared to other HSDTs models. The
material properties of FG-plate are supposed to vary across the thickness of the plate according to power-law mixture. The
differential governing equations are derived based on the virtual working principle. Numerical outcomes of bending analysis of
FG plates under hygro-thermo-mechanical loads are performed and compared with those available in the literature. The effects
of the temperature, moisture concentration, elastic foundation parameters, shear deformation, geometrical parameters, and
power-law-index on the dimensionless deflections, axial and transverse shear stresses of the FG-plate are presented and
discussed.
