Abstract
There are many nondestructive evaluation tasks in which the ability to determine the state of stress in a component would be invaluable. Of the techniques potentially at our disposal, only the use of ultrasonic probes offers any real possibility of measuring stress below the immediate surface region. Acoustic measurements based on the acousto-elastic effect have been successfully demonstrated for determining the cross-sectional variation of stress for specimens in plane strain.1 Until now there has been little success in measuring stress distribution through the thickness of a specimen. In this paper we outline a theory and an initial experiment with a new technique which is capable of determining the distribution of stress in a solid body in three dimensions.
