  7. 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 , buy q690d plate thickness


    For metals such as steel there is a stress at which the fatigue life becomes infinite (i.e. material does not fail by fatigue). 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
