Abstract
Functionally graded materials (FGM) are a class of composites, in which the properties of the material
gradually change over one or more Cartesian directions, the combination of which results in an assembly
with higher performance than components taken separately. This class of composite materials has gained
considerable attention in the engineering community, especially in high-temperature applications such as
nuclear reactors, aerospace, and power generation industries. The aim of the current work is to study the
influence of homogenization (idealization) models and thermal loads on static deflection behavior of sandwich functionally graded plate. Several micromechanical models have been employed to obtain the effective
material properties of the two-phase FGM plate. The FGM plate is subjected to linear and no linear thermal loads. The integral theory used contains only four variable functions as against five in the case of other HSDTs. The governing equation are derived and resolved via virtual work principle and Navier’s model.
The accuracy of the proposed analytical model is confirmed by comparing the results with those given by
others model existing in the literature.
