Model assisted probability of detection analysis for nondestructive evaluation of complex shaped parts

There is an increasing need to do predictions of systems for non-destructive evaluation (NDE) in a fast and cost effective way. This depends on the high demands of quality in the aerospace industry and the need to take full responsibility of components in a life-cycle perspective. The project is a part of the research cluster Strength and Lifing at GKN Aerospace Engine Systems, with the aim to address the need to handle actual physical properties of the component, in terms of defects and their distribution, and develop an integrated cross-disciplinary approach where inspection techniques and lifing methodology cooperate. Focus lies in the use of mathematical modeling in order to estimate the capability and reliability of NDE procedures, and the project is a continuity of a European collaboration project in this field. The results that will be achieved within the project are developed models that are capable of handling all parameters relevant for an inspection with the eddy current method, which is often used for critical inspections. Methods for optimization and for linking the model based estimation of NDE procedure capability to fracture mechanical properties and component life will be a result of the project.
