Abstract: This paper discusses the gradation and thickness effect on plates made up of functionally graded material (FGM) under the action of coupled thermo-mechanical loading. In this study, a plate made up of FGM is applied with a coupled thermo-mechanical loading and the combined effect of temperature gradient along with the action of mechanical loading is observed on the plate. Using obtained results, a material can be tuned for specific kinds of applications by varying the volume fraction exponent and plate thickness. Further, efforts have been made to reduce the mass of the structure preventing the failure of the FGM plate thermally and from stress point of view. The whole analysis is carried out in finite element tool ABAQUS. Results obtained can act as a guiding principle for selection of a particular type of gradation and the limiting value of thickness of the structure for a specific kind of application.

Keywords: functionally graded materials; FGMs; finite element analysis; ABAQUS; UMAT.
