Summary

Impellers and blades are key components of turbomachines, and fatigue is their main failure mode. Fatigue research on impellers and blades has been systematically reviewed, covering fatigue failures, numerical simulations, and fatigue tests in various turbomachines. High cycle fatigue caused by vibration is the main failure mechanism, with fatigue cracks usually initiating from stress concentration locations. Resonance from aerodynamic loads is a primary cause of fatigue failure in steady operating conditions. Future research directions include combining meshless and finite element methods and conducting combined fatigue tests on actual impellers and blades.
