Functionally Graded Materials (FGM) has continuous variation of material properties from one surface to another. The gradation of properties in an FGM reduces the thermal stresses, residual stresses, and stress concentrations found in traditional composites. This paper will explore analysis of FGM flat plates under pressure i.e. thermal loading in order to understand the effect variation of material properties has on structural response. Theoretical formulation of various material properties is done using Rule of mixtures. The plate is then modeled and subjected to specific boundary conditions after which thermal analysis is carried out. The convergence studies with respect to varying mesh and layers are carried out in order to obtain accurate results. When subjected to thermal loads, the displacements and stresses vary with different metal/ ceramic proportions, in addition to this; deflection also varies greatly through the thickness. the variation of the same parameters with changing volume fraction of ceramic is also understood. Results are compared to published results in order to show the accuracy of modeling FGMs using ANSYS software.
