A new design method for the fatigue-simulating specimen of Twin-web turbine disk was proposed, and the simulated specimen was designed. Results showed that the maximum stress, stress gradient and equivalent detrimental volume were similar between the specimen and the turbine disk, and their reliability lives were basically the same.
