| Résumé | Quantitative risk assessment (QRA) is now required by most aircraft structural integrity programs. One of the key components of an accurate QRA resides in the accuracy of the fracture mechanics modelling of multiple site fatigue damage (MSD) scenarios, which is used to generate the MSD crack growth curves. This paper presents the results on the development of fracture mechanics models for MSD problems in order to carry out a QRA. To address this complex problem, NRC developed a crack growth analysis (CGA) software, which is capable of calculating the β-solutions for stress intensity factors and the remaining life of MSD in built-up structures (aircraft wing panels). The β-solutions were calculated by superposition of several closed-form and numerical solutions. Comparison between NRC's CGA β-solutions and p-version finite element analysis (FEA) results for various MSD scenarios are presented in this paper. Good agreement was obtained between NRC's CGA results and FEA results. |
