    Abstract
  • For analyzing the aircraft structural reliability under bad parking conditions, probability damage tolerance evaluation method is established. This method is used to analyze the reliability of multi-crack structure considering the influence of pre-corrosion. This method comprehensively surveys the existed single-crack propagation random model under pre-corrosion conditions using Wei-Landes linear theory and the crack propagation random model with multi-crack structure. Finally, the life-reliability curves are given in an illustrative example using the method as indicated above. Comparing the reliability curves of different SUS(Service Usage Severity), the influence of pre-corrosion and SUS to crack propagation life can be obtained.
