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

The use of ultrasound for immersion mode quantitative nondestructive evaluation depends on our ability to model the interaction of the incident beam with the water-solid interface. The effects of surface roughness on the inspection process may be crucial. For example, ultrasonic images of interior flaws will be degraded due to the random fluctuations in the wave front of the incident field [1,2]. Similarly, surface roughness also affects the characterization of porosity in solids from the ultrasonic attenuation [3] since the attenuation is commonly determined by comparing the reflection from the backsurface with that from the front surface of the part.
