Fatigue testing of the fir tree root of a turbine blade
Original language description
The present paper deals with the low cycle fatigue of a low pressure steam turbine blade. Nonlinear FEA modeling is used to determine the strain and stress distribution. The lifetime is predicted employing LPSA method in conjunction with uniaxial fatiguecriterion SWT. Experimental testing procedure to verify the FEA analysis and lifetime prediction is described. Strains measured employing strain gauge measurement are compared to numerically calculated strains. Predicted lifetime is compared to experimentally determined lifetime and the reasons of differences are discussed.
