Functionally graded materials (FGMs) have received considerable attention in many engineering applications since they were first reported in 1980s. FGMs are composite materials, microscopically inhomogeneous, in which the mechanical properties vary smoothly and continuously from one surface to the other. Compared with classical laminated composite materials, FGMs provide superior thermo-mechanical performances under given loading circumstances. FGMs can be used to improve creep behavior, fracture toughness of machine tools, wear resistance, oxidation resistance of high temperature aerospace and automotive components and so on. It is the intention of the present study to examine the effect of geometric nonlinearity on displacements and stresses in beams made of functionally graded materials (FGMs) subjected to thermo-mechanical loadings by using the ANSYS. The results obtained from this method are compared with the displacements and stresses of the beam are obtained based on a first-order shear deformation beam theory (FSDBT).
