A model describing crack length distribution is proposed on the basis of experimental laws governing the formation and growth of fatigue cracks in a flat specimen with multiple stress raisers. The density of this distribution corresponds to that of Pareto and can be used to describe the accumulation of scattered defects in a wide range of cracking...

In the case of cyclic loading of aircraft structures, fatigue cracks are initiated and grow in riveted joints, which may lead to a decrease in the residual strength and to the sudden widespread fatigue damage. This phenomenon is induced by multiple-site damage, which is usually described by statistical methods. Since the crack length in multiple-si...
