Levy method for bending analysis of composite plate resting on a Winkler elastic foundation hypothesis is presented based on classical plate theory. Two models were considered for a composite coated plate. These two models were named conventional composite model and functionally graded coated model. The conventional composite model was consisting of a ceramic Homogeneous Coated (HC) layer and metal layer. The Functionally Graded Coated (FGC) model was consisting of Functionally Graded Material (FGM) as a composition of ceramic and metal on a metal layer. The material properties of FGM composite are assumed varying exponentially along the thickness direction. Also, the material properties of the nan-FGM layers are assumed homogeneous. Finally, the effect of the FGC layer, as well as, the elastic stiffness of the foundation is presented and compared with the results of the HC model.
