Concepts and Techniques for Ultrasonic Evaluation of Material Mechanical Properties.

Abstract

The purpose of this paper is to review ultrasonic methods that can be used for material strength prediction and verification. Emergent technology involving advanced ultrasonic techniques and associated measurements is described. It is shown that ultrasonic NDE is particularly useful in this area because it involves mechanical elastic waves that are strongly modulated by morphological factors that govern mechanical strength and also dynamic failure modes. These aspects of ultrasonic NDE will be described in conjunction with advanced approaches and theoretical concepts for signal acquisition and analysis for materials characterization. It is emphasized that the technology is in its infancy and that much effort is still required before the techniques and concepts can be transferred from laboratory to field conditions. (MM)
