The studies of probabilistic distribution of fatigue crack growth life (or the fatigue fracture probability) have been reported. However, some studies have concluded that each crack grows independently, without crack coalescence; while others indicate the defects should be treated as 2-dimensional cracks. In this study, a method to predict the probabilistic distribution of fatigue crack growth life that considers crack coalescence of the surface crack at the welded line is presented, and the influence of several parameters on the life distribution is discussed.
