Abstract
Prediction of catastrophic and costly failures in structural components has been hampered by the inability to measure stress levels in critical components with accuracy. This proposal descirbes the steps needed to develop a stress measurement system that relies on ultrasonic (acoustoelastic) wave measurements. The recent advancements made in the use of critically refracted longitudinal waves (CRLW), coupled with expansion of computer-assisted ultrasonic detection systems, have given impetus to this proposal. This study involves the analysis of thr CRLW phenomena, identification of state-of-the-art support apparatus, experimental verification of fundemental premises, and the development of a design specification for a stress analysis system.
