A fatigue model based on cummulative damage is developed
for predicting the fatigue life of fiber-reinforced
polymeric composites in offshore applications. This
model incorporates applied maximum stress, stress
amplitude, loading frequency, residual tensile modulus,
and material constants as parameters. The model is
verified with experimental fatigue data of a glass
fiber/vinyl ester composite in various environments.
While the specimens are exposed to air, fresh water, and
sea water at 30 deg C, they are subjected to
tension/tension stress at four levels of applied maximum
tensile stress in each of two frequencies. Both the
residual mechanical properties at specified loading
cycles and the number of cycles at which the specimens
fail are measured. These data are used to determine the
