Steels - Endurance Limits and Fatigue Stress - The …
Most steels have an endurance or fatigue limit about half the Tensile Strength. Tensile Strength - (Ultimate Tensile Strength) - of a material is the limit stress at which the material actually breaks, with sudden release of the stored elastic …
Fatigue limit - Wikipedia
The fatigue limit or endurance limit is the stress level below which an infinite number of loading cycles can be applied to a material without causing fatigue failure. Some metals such as ferrous alloys and titanium alloys have a distinct limit, whereas others such as aluminium and copper do not and will eventually fail even from small stress amplitudes. Where materials do not have a distinct limi…
