Abstract

In order to contribute to the development of a methodology for risk assessment (fatigue reliability) and lifetime prediction for safety critical metallic components, the risk assessment and lifetime prediction for critical metallic components are studied. First order reliability method (FORM) is used and application to weep hole cracks in C141 wing is analyzed. A novel method of fitting a closed form mathematical expression for probability of detecting (POD) to experimental C-scan data from C141 weep holes was used in the analysis. FORM methods are combined to compute fatigue reliability for the weep hole configuration. The method shows promise for development as a standalone personal computer based system for structural integrity and reliability assessment.
