Abstract. This paper concentrates on the finite element analysis of thermoelastic stresses, displacements and strains in a thin circular functionally graded material (FGM) disk subjected to thermal loads. Further the temperature profiles have been modeled with the help of heat conduction equation. The model has been solved numerically for an Al2O3/Al FGM disk. The numerical results reveal that these quantities are significantly influenced by temperature distribution.
