Research in Quantitative NDE Techniques.
Abstract
Analyses of nonspecular reflection of acoustic waves from an interface between a fluid and both a planar, layered halfspace and a corrugated halfspace were conducted. Dispersion of the velocity, the Schoch displacement parameter of leaky Rayleigh waves, and the amplitude distribution of the reflected field were studied. For the Planar halfspace one exact and two approximate models are presented. In a study of reflection of Rayleigh surface waves from surface cracks, it was found theoretically and confirmed experimentally that transverse in-plane stresses in the surface wave cause reflections from cracks oriented normal to wavefronts. Several studies were conducted on the interaction of ultrasound and fibrous composites.
