It has been over 15 years since the first edition of this book was published. In that period, the use of models in the ultrasonic NDE field has seen a steady growth. Model-based ultrasonic NDE simulation packages were in their infancy when the first edition appeared, but now both research-grade and commercial software packages are available. Thus, it is more important than ever to understand the fundamental physics and mathematics behind ultrasonic NDE models. Another notable change has been the development of models to aid in the evaluation of NDE reliability and flaw detectability. This application of models has been termed model-assisted probability of detection or “MAPOD.” Also, starting in 2001 a series of ultrasonic benchmarks were sponsored by the World Federation of NDE Centers and the results presented at the annual Review of Progress in Quantitative NDE meetings. The aim of the benchmark studies was to validate modeling assumptions and compare the results of different modeling approaches to experiments on well-characterized samples. Such efforts, which continue today, are extremely important for models to gain a much wider acceptance and use by the NDE community.
Two books by the author have appeared since the first edition that can be considered companions and extensions of this book.
