Fatigue crack initiation and growth from artificial pits of different depths has been studied. The experimental results were analyzed using fracture-mechanical models including those for small cracks. The model shows very good agreement with experiment in describing the initiation and growth of a fatigue crack emanating from the pit and in predicting the dependence of reduction of fatigue life on pit size. Also an empirical relation between depth of the corrosion pit and fatigue life has been established. A microradiographic method for corrosion pitting depth determination has been described.
