    Fatigue Limit and Fatigue Strength. The hor­ izontal portion of an S-N curve represents the maximum stress that the metal can withstand for an infinitely large number of cycles with 50% probability of failure and is known as the fatigue (endurance) limit, Sp Most nonferrous metals do not exhibit a fatigue limit. Instead, their S-N

    For glass fiber-reinforced epoxy, data produced by Dharan (1975) suggested that the fatigue limit of epoxy, found to be at 0.6%, was a good approximation to the UD composite fatigue limit at three different fiber volume fractions (0.16, 0.33, and 0.50). However, for composites with stiffer carbon fibers, the fatigue limit is usually higher than 0.6%.
