Overview of Ceramics Project

As was discussed previously, an important element in the development of a quantitative NDE technology is the coupling of nondestructive measurement results, failure modeling, and risk analysis to produce an accept/reject criteria. This basic philosophy was first formulated from first principles in the context of a project to produce a quantitative inspection capability for ceramic materials. In this paper, the history of this project is reviewed and the plans for this year\u27s program, whose results you will hear today, are described

Quantitative Ultrasonics—Overview

I would like to give an overview of our work in quantitative ultrasonics in the ARPA/AFML program. The goal is to use ultrasonics to determine failure related or fracture critical properties of a flaw. In practice , this implies the use of ultrasonics to determine the geometric shape of the flaw: its size, its shape and its orientation with respect to a stress field
