Probability of failure and risk assessment of structure with fatigue cracks. (English) Zbl 0823.73049
Summary: A methodology is proposed for the evaluation of the reliability of a cracked structure with uncertainties in external loadings, material properties, and initial crack geometry. The methodology consists in determining the probabilistic crack path and calculating the cumulative probability of failure for mixed-mode crack propagation. The performance of the methodology is demonstrated by mode I and mixed-mode fatigue crack problems.
