Theoretical Studies of Ultrasonic Scattering and Defects,
Abstract
In this year's research we have completed theoretical work, but placed special emphasis on attempts to make contact with the experimental situation for laboratory prepared flaws in determined geometries - (a step closer to the real world ). In particular, we tried to identify some general features or indices that might be useful in evaluation of scattering data for NDT. In the course of our most fruitful interactions with the experimental groups at Rockwell and Tennessee we learned about the needs and the formats most convenient for them, and have developed a library of computer programs for various scattering situations. We have also investigated other approximations (static, quasi-static), which may be better in certain limits, and started to evaluate them in comparison with exact and experimental data. Programs have been developed and used. Finally, we have begun to implement the scattering theory for defects other than holes or inclusions, particularly scattering by flat cracks. We proceed with details of the studies.
