“…The data used to develop closed-form solutions for each crack tip were obtained from a previous (2004) AFRL in-house effort [6] to characterize the effect of an open hole on an adjacent through crack. The finite element data 7 were spline fit to develop a table look-up solution for each crack tip.…”

“…The code, named PISA (Probabilistic Investigation for Safe Aircraft), is able to simulate the nucleation and subsequent growth of interacting cracks in aerospace metallic components, such as riveted joints and stiffened panels, until the final failure . There are some computer codes already available such as NASGRO and AFGROW, which are used for damage tolerance design of aerospace components by simulating the propagation of cracks in different geometric configurations. The PISA code differs from these codes because, even if it carries out a deterministic calculation of the cracks growth for each simulation, it is organized to be used for a probabilistic design, in order to evaluate the probability of failure of structural components …”

This article deals with the fatigue propagation of multiple cracks in finite width holed panels, which are typical of aircraft structural components. Theoretical studies in the literature have been considered and critically analyzed. Some of them have been translated into analytical models and implemented in a computer code. To check the effectiveness of the used models, a fatigue testing campaign has been conducted on six different configurations of notches and cracks. The comparison between experimental results and those obtained from the implemented models has shown a good agreement
