abstract

A fracture mechanics-based methodology is presented for determining equivalent initial flaw size (EIFS) distributions from field inspection data accounting for different service histories of fracture critical components. The EIFS distribution based on inspection data from a subset of the fleet allows for an assessment of initial material/manufacturing quality and enables a probabilistic fracture mechanics-based fatigue life prediction for the fleet as a whole. The methodology is demonstrated on an industrial gas turbine blade experiencing in-service cracking.
