Abstract
The long term reliability of structural ceramic components is of major interest and concern to those involved in design, manufacturing, testing and use of such components [1,2]. Flaw population data generated at a high probability of detection and high confidence level using improved NDE technology undoubtedly provide a reliable method for safe design at a lower cost as illustrated by the concept in Fig. 1. The concept demonstrates that more flaws with smaller size distribution may be detected at higher probability/ confidence level (compare dotted areas under the two flaws distributions 1, 2) with the use of appropriate NDE techniques and technique development.
