The analysis consists in extracting the elementary cycles from a history of stress loading.

  • First call to POST_FATIGUE:

The elementary cycles are extracted using the cycle counting method RAINFLOW, based on the loading history \({\sigma }_{1}(t)\).

  • Second call to POST_FATIGUE:

The elementary cycles are extracted using the cycle counting method RCCM, based on the loading history \({\sigma }_{1}(t)\).

  • Third call to POST_FATIGUE:

The elementary cycles are extracted by the cycle counting method RAINFLOW, on the loading history \({\sigma }_{2}(t)\) and a stress concentration coefficient \({K}_{T}=2\) is used.

  • Fourth call to POST_FATIGUE:

The elementary cycles are extracted by the cycle counting method RCCM, on the loading history \({\sigma }_{2}(t)\) and a stress concentration coefficient \({K}_{T}=2\) is used.
