Fatigue Characterization of Composite Materials

Source

A procedure is outlined that allows the generation of an S-N curve with some statistical value without resorting to an extremely large data base. The procedure is based on a power law representation of the S-N curve and a two-parameter Weibull distribution for time-to-failure at a specific stress level. A data pooling scheme is also discussed that allows the determination of a fatigue shape parameter that is independent of stress level.
