Topics on scattering of ultrasonic waves by subsurface cracks, the effects of the edges of samples on eddy-current flaw evaluation, ultrasonic reflection from a stressed interface, ultrasonic signal processing for multilayered NDE, and flaw characterization by power spectrum matching are presented. Consideration is given to modeling of ultrasonic flaw detection, development of an acoustic model for multilayered NDE, ultrasonic pulse-echo techniques for curved surfaces, identification of deformation mechanisms by classification of acoustic emission signals, and analysis of pulsed thermal inspection. In addition, a translucency test, a fast-recovery high-voltage pulser for ultrasonic transducers, and an acoustical holographic/pulse echo pressure vessel imaging system, using computer reconstruction and multi-image integration techniques, are described.
