tolerances resulted to play the lowest contribute in terms of added life dispersion, followed by the actual loading conditions. Finally, the material scattering contribute resulted to be the most important uncertainty source that should be always considered for every rigorous structural integrity assessment. The presented approach can be used to provide numerous essential information such as: probabilistic life assessments, probability of failure, probability of having crack propagation under given conditions, uncertainty quantifications and sensitivity analyses.
