| Abstract: | Analytical model for axial symmetrical functionally graded materials(FGM) is established based on the elasticity theory and computational mathematical model. The boundary conditions of the model is determined according to its application background. Triangle series are employed to describe the thermal stress caused by the difference of thermal expansion coefficients. Thus the accurate stress distribution has been calculated. |

| Keywords: | RGM axial symmetrical RGM thermal stress relaxation |
