A stochastic approach to fatigue damage of carbon fiber composites (CFRP) was proposed. It is based on the constitutive equation for fatigue damage in continuum damage mechanics. By introducing the stochastic process to this equation, a stochastic differential equation of Itô type was derived. The sample path and life distribution of fatigue damage of CFRP were obtained by using the solution of the stochastic differential equation and its probability density, respectively. These theoretical results were compared with the experimental data for a carbon eight-harness-satin/epoxy laminate.
