Advanced Structural Analysis/Part I - Theory/Failure Modes/Fatigue/Crack Initiation/Loading
Fatigue life is influenced by virtually every thinkable aspect of the applied loading history, such as:
- Stress amplitude
- Mean stress
- Loading frequency
- Loading direction
- Combined effect of complex stress filed
The effect of some of these influences can be quantified with fairly good accuracy whilst the effect of other influences must be regarded in a more qualitative sense.
