In this study, elastic stress analysis of a thin circular disc made of functionally graded materials (FGMs) subjected to a temperature load and an inertia force due to rotation of the disc is investigated. Based on the two dimensional thermoelastic theories, the axisymmetric problem is formulated in terms of a second order ordinary differential equation which is solved by finite difference method (FDM). The FGM disc is assumed to have exponential variation of material properties in radial direction only and Poisson's ratio is kept constant. The result also compared with semi-analytical solution (SAS) and their consistence has been shown. Some numerical results of thermoelastic field are presented and discussed for an Al2O3/ZrO2 FGM.
