Progress in the theory of ultrasonic flaw detection. Problems and prospects

This paper was prepared upon request from the organizers of the XVIII St. Petersburg conference Ultra-sonic Flaw Detection in Metal Structures. UZDM 2004. The progress made in the theoretical issues of ultrasonic flaw detection over the past 20 years is briefly considered, and some practical issues are discussed. Specific problems that are waiting to be solved are formulated, and the authors opinions about the prospects of developments in ultrasonic flaw detection are presented. The preparation of the paper was much facilitated by book [1], which was published recently.Translated from Defektoskopiya, Vol. 40, No. 10, 2004, pp. 13–48.Original Russian Text Copyright © 2004 by Ermolov.
