Corrosion and fatigue are two types of damages found in aircraft and offshore structures. Corrosion fatigue processes are characterized by randomness due to the random nature of materials, initial defects, loading, and environmental condition. In this study, a mechanistically based probabilistic model for prediction of pitting corrosion fatigue life in aluminum alloys has been developed which captures the effect of the interaction of cyclic load and corrosive environment and all the stages of the corrosion fatigue process. Monte Carlo simulations were performed to define the failure probability distribution. Predicted cumulative distribution functions of fatigue life agreed reasonably well the experimental data.
