Abstract
Fatigue strength allowables required for the application of life prediction methodologies for glass fiber-reinforced composite laminates can be derived experimentally for a number of different constant amplitude loading cases. Mean or median stress and lifetime values are then used in order to constitute mathematical stress-life curves for the representation of the available fatigue data. However, a higher reliability level is needed for design purposes, and statistical analysis of the fatigue data is therefore necessary. Common methods for the derivation of reliability-based S–N curves for fiber-reinforced composite materials are presented in this chapter.

It can even be argued that this should be 0.25 cycles to failure, or 0.75 cycles to failure, if the load is sinusoidal starting with tension, and the failure mode is tensile or compressive, respectively.
