Abstract :
Finite element method was used to compute the thermo-elasto-plastic stress and strain fields of turbine blade according to typical loading spectrum. Controlled-strain test of turbine blade material was carried to get some necessary parameters used in life prediction formulas. On the basis of the above analysis, fatigue life of gas turbine blade was estimated.
