Scattering from voids in solids in the intermediate wavelength regime

Abstract

The main objective of this work was to develop techniques of non-destructive testing and give them a strong theoretical underpinning to render them as quantitative as possible. Thus in ultrasonic testing the objective was to combine the traditional manual search for flaws with computer automated search and elastic scattering theory to provide quantitative data on location, size, shape, and orientation. This approach led to several schemes to solve the Inverse Scattering Problem or the reconstruction of a flaw from just a few reflected ultrasonic echoes. Early efforts led to successes with idealized man-made flaws consisting of single and compound flaws embedded in Titanium-alloy. Later this work produced results with naturally occurring flaws in aerospace components.
