Virtual cracks and the future of inspection reliability

Research output: Contribution to conferencePaperScientific

Abstract

One long standing issue in NDE training and qualification is the availability and cost of relevant flawed test blocks. A typical qualification mock-up contains limited number of realistic flaws due to time and cost limitations. Increasing automated inspections offer new possibilities to overcome these limitations. In automated inspections, the data gathering and analysis phases are separated. This allows the introduction of flaw signal into the data, that were not present in the original data. On the other hand, the representativeness of these "virtual flaws" need to be confirmed.

This presentation review's the the state of the art of this new technology shows how virtual flaws can be used to improve NDE reliability and performance demonstration. POD determination using virtual flaws is explored. Finally, some future possibilities offered by this technology are introduced.
