Calculate fatigue stress limit from fatigue limit cycles (DNVGL-RP-C203 section 2.11).
The fatigue stress limit is the stress threshold for the onset of fatigue damage. For cyclic stress values below the fatigue limit, a fatigue check is not required. For accumulated damage (Miner's rule), the maximum stress must be less than the faigue limit. The fatigue limit only applies for carbon steel and some other materials, and for certain conditions. For other cases the fatigue limit does not apply.
