Fatigue Retardation Due to Creep in a Fibrous Composite

Source

A series of experiments were performed in an attempt to investigate the effect of creep strain and temperature on the fatigue life of a [±45]2s graphite/epoxy composite laminate. The experimental results indicate that sustained periods of static loads have significant retardation effects and that cyclic loading with a lower frequency preceeding one with a higher frequency also prolongs the fatigue life.
