  3. Fatigue limit - Wikipedia

    Fatigue limit, endurance limit, and fatigue strength are all expressions used to describe a property of materials: the amplitude (or range) of cyclic stress that can be applied to the material without causing fatigue failure. Ferrous alloys and titanium alloys have a distinct limit, called the endurance limit, which is the amplitude of completely reversed bending stress below which there best s355j2wp fatigue limit

  4. Establishing Fatigue Properties of Ultra High Strength ...

    fatigue test data are then usually plotted on a semi-log coordinates, this is called a Whler diagram or a S-N diagram (Lee 2005). To this data a curve can be adapted, this is called the Whler curve or the S-N curve. Fatigue limit for steels can be decided by these curves, the fatigue limit is the amplitude where no fatigue fractures occur.


    The fatigue strength for this case is referred to as the endurance limit. Other materials such as aluminum alloy have no endurance limit, so an arbitrary fatigue life must be chosen (eg. 10 million cycles, 1 million cycles, 100,000 cycles or some other relevant life).
