Pitting corrosion may have an important influence on the structural integrity of different components used in civil, nuclear, and aerospace engineering because fatigue cracks usually initiate from corrosion pits. It was important to develop a responsible approach to predict the remaining life. An analytical model for the prediction of crack initiation life caused by pits under the interaction of fatigue load and a corrosive environment was proposed in this paper. The effect of the aspect ratio of the pit on the crack initiation life was considered in this model. Compared with the limited experimental data available in the literature, the crack initiation lives predicted by the proposed model agreed well with the experimental data.
