Initiation and Propagation Characteristics of Multi-Source Fatigue Crack in Superalloy Disk
The multi-source fatigue crack growth characteristics of a turbine disk were studied via high-speed rotating low cycle fatigue test, fracture analysis and crack growth simulation analysis. The results show that the fatigue initiation life N0 of Superalloy disk and its simulation parts is less disper...
