摘要：

This paper presents a method for simplified fatigue stress analysis for large catamaran based on implied cumulative fatigue criterion. A probabilistic fracture mechanics model for fatigue life prediction is introduced. Probabilistic fracture mechanics approach is calibrated to an SN approach to better account for crack initiation and initial crack size. The fatigue reliability of the considered structural details is modeled as a series system considering the fact that fatigue clacks may occur at many locations. Subsequently, the effect of inspection on the system fatigue reliability is exemplified with the aim at probabilistic inspection planning.
