Ultrasonic Texture Analysis for Polycrystalline Aggregates of Cubic Materials Displaying Orthotropic Symmetry
The study of the applications of the acoustoelastic effect, i.e. the stress-dependence of the propagation velocity of ultrasonic waves in deformed elastic media, has undergone considerable progress in recent years.1 Techniques for the determination of applied and residual stresses have been proposed both for bulk2–5 and for surface6–9 ultrasonic waves. However, for the practical application of these techniques to fabricated materials, the difficulty of separating the often competing effects of stress and texture remains a vexing problem.
