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