Fatigue endurance limit is determined on the basis of an S-N curve where the limit of 10 7 cycles .

How can the endurance limit for a fatigue analysis be calculated when real material properties are not available? It is always best to use measured data for the input of the endurance limit (and corresponding cycles at endurance) when performing a fatigue analysis.However,finding such data can be difficult.When such data is not available,it may be possible to estimate the endurance limitFatigue limit state design of fast boats - ScienceDirectSep 01,2017 s355j2b fatigue lbimit#0183;The fatigue limit is 75 MPa (see Fig.11) and the cycles at lower stress will not affect the fatigue life.4.Conclusions.A direct calculation method was developed to address the fatigue limit state of a planing boat.The method considers hydro-elasticity,dynamics and non-linearity in geometry and material.A new stress range spectrum was Fatigue limit rules of thumb - Aircraft engineering - Eng-TipsApr 16,2009 s355j2b fatigue lbimit#0183;Greg is correct,the endurance limit is essentially a myth.Numerous studies performed in the gigacycle (10 9) regime confirm that steels have reduced fatigue strength when compared to conventional run outs at 10 7 cycles.The following is a Google search using very high cycle fatigue and gigacycle fatigue as keywords:

Fatigue limit is not only of interest from a fundamental viewpoint,it is also of practical importance for designing durable structures.The concept of a limiting condition for fatigue,similar to a yield stress for metal plasticity,came from observing that the fatigue life of some metals,particularly steels,was essentially infinite (or much longer than needed for safe performance in most
