Transfer of POD Performance Capabilities from Simple Shapes to Complex Shapes
Abstract
The demand for quantified nondestructive evaluation (NDE) has increased significantly with increasing use of damage tolerance in engineering design and acceptance. The metric that has been developed to quantify NDE capabilities and to provide a method of data exchange is the probability of detection (POD). Generation of a characteristic POD curve requires: (1) passing a statistically significant number of representative flaws through and NDE procedure; (2) the flaw distribution must be near the expected NDE detection threshold; (3) flaws located in representative materials, geometries and surface conditions; (4) systematic control of NDE procedures; and (5) documentation of the results of application [1–3].
