Abstract
Risk based inspection strategies rely on detailed knowledge of the performance of inspection techniques. It is well known that every inspection technique has limitations in terms of reliability and effectiveness. Moreover, these are influenced by many factors. E.g. it depends on operator skills, inspection procedure, defect and object geometry as well as technique specific instrument properties and settings. The objective of the "POD generator" project is to develop a numerical modeling approach to assess inspection effectiveness for a specific technique and situation flexibly and reliably yet at acceptable costs. Besides the models to simulate various degradation mechanisms, numerical models have been developed and validated for accurately simulating the physics of inspection techniques. Also the human factor is taken into account. These numerical models are then used to generate quantitative probability of detection (POD) curves. This will be illustrated for ultrasonic time-of-flight-diffraction (TOFD) inspection of fatigue cracks. © 2009 American Institute of Physics.
