Thermo-Mechanical Bending of FGM Plates Resting on Elastic Foundations by Hyperbolic Shear Deformation Theory

Bending response of simply supported ceramic-metal FGM plates resting on Winkler-Pasternak elastic foundations and subjected to thermo-mechanical loadings is investigated in the present study. Material properties are assumed to vary according to power law in terms of constituents. The hyperbolic shear deformation plate theory is employed. This simple theory does not need shear correction factor and satisfies free stress conditions on plate surfaces. Governing equations are derived using principle of virtual work and solved by Navier method. The accuracy and efficiency of the present formulation are demonstrated by solving some benchmark problems. Also the effects of thermo-mechanical loading, foundation parameters, side to thickness ratio and volume fraction index on the results are investigated.
