Abstract:

Further exploration of ultrasonic beam interactions has been conducted and a review of the state-of-the-art is given. Improvement in the measurement of absolute intensities and an independent evaluation of the third- order elastic constants has permitted a fairly accurate comparison between theoretical predictions of intensity of interaction and experimental results. A four-beam interaction is also shown to be weaker than the previously observed three-beam interaction. A discussion is also directed toward the energy partition that occurs when ultrasonic beams impinge on a liquid-solid boundary. An ultrasonic goniometer is described for partial investigation of this energy partition. Experimental results are given for various metals and layered composites.
