Effects of Plastic Deformation on the Inference of Stress and Texture from the Velocities of Ultrasonic Plate Modes
Considerable attention has been given recently to techniques for predicting stress and texture from the angular dependence of the velocity of guided ultrasonic modes in plates [1–4]. The analysis on which the measurements are interpreted is based on the continuum theory of elasticity. No influence of stress induced dislocation motion on the velocity is considered and plastic deformation only enters the theory through the changes in texture sensitive elastic constants, induced by such processes as grain rotation.
