Inspection Based Probabilistic Modeling of Fatigue Crack Progression

摘要

This paper focuses on one of methods which can be used for reliability assessment of structures which are subject to cyclic loads. A particular attention is paid to creation and propagation of fatigue cracks from edges and surface. On the basis of the reliability assessment, a system of inspections is proposed for structural details which tend to be sensitive to fatigue damage. A new method which is still under development - Direct Optimized Probabilistic Calculation ("DOProC") - was used for this probabilistic task. This method is the basis of the FCProbCalc software.
