Fatigue Failure

Introduction:

Fatigue failure is the main form of early failure of the mechanical parts, the main purpose of fatigue study is precisely estimate the fatigue life of the material structure parts to ensure fatigue failure would not occur during the service period. It includes the following items: symmetrical cyclic fatigue stress, non-symmetrical cyclic fatigue stress, strain fatigue (low cycle fatigue), fatigue crack propagation rate, thermal fatigue test, corrosion fatigue test, contact fatigue test, fatigue test at high temperature and fatigue test at low temperature.

Testing standards:

ISO 12108、GB/T 15248、GB/T 10622、ASTM E647 etc.
