The application of fatigue limits in calculation of material coefficient k leads to total scatter band of fatigue life higher than 4. For S355J2WP steel good conformity of the calculated and experimental fatigue lives with total scatter band around 2.7 is obtained using the Findley and Matake criteria for the k coefficient determined under 3 10 5 cycles.

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

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.
FATIGUE OF COMPOSITES - unitn.it
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).

Fatigue of Threaded Fasteners - ASM International
Fastener fatigue Fatigue is the most common form of frac-ture of metal structures, accounting for up to 80% of all costs associated with fracture. Fas-teners are no exception, as fatigue remains the most common cause of fastener breaks. Fatigue crack initiation and growth occurs when cyclic stresses exceed the fatigue strength of local ma-
