Description

The damage tolerance approach to structural safety is based on the predicted growth of the “largest” crack that could be present in a structure at the start of a usage period1–4. The length, aNDE of this potential crack has generally been determined by correlating crack size with the reliability of the non-destructive evaluation (NDE) system employed during structural inspections. Since many factors other than crack length influence detectability, NDE reliability as a function of crack length must be expressed as a probability of detection (POD) and must be estimated from a demonstration experiment whose results are non-deterministic.
