Review of Progress in Quantitative Nondestructive Evaluation
Center for Nondestructive Evaluation

Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.

This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract

Of strong practical interest in the subject of fracture mechanics and related structural design and damage are the surface-breaking and sub-surface cracks. Indeed the scattered-wave fields generated by the interaction of incident surface or body waves with these cracks would be expected to yield most of the important in-formation about the geometries of the cracks. It follows, in the subject of quantitative non-destructive evaluation (QNDE) there is considerable interest in scattering by surface-breaking and sub-surface cracks, as important steps in solving the inverse problems of obtaining the crack geometries from the scattered wave fields. However, having the solutions to the corresponding direct problems is a prerequisite to the inverse problems.
