主　　题：functionally gradient material (FGM) Moire interferometry concentration of thermal stress. 

摘      要：Studies of displacement fields and stress concentration, due to uniform temperature change in a functionally gradient material (FGM) specimen and bimaterial (NFGM) specimen, have been made by Moire interferometry and finite element method. Results show that the thermal stresses concentration has been effectively reduced, and the distribution of the thermal deformations and thermal strains have also been relaxed and improved by transition layer of FGM.
