Nonlinear Acoustics.

Abstract

Nonlinear properties of solids and liquids are studied. Both pulsed and cw ultrasonic waves are used in the ultrasonic measurements which are made by electronic as well as optical techniques. Nonlinear properties of solids such as single crystal KZnF3, Ge, Si, NaCl, etc. are described in terms of third-order elastic constants which can be measured between room temperature and 4 K; those of liquids are described in terms of the ratio B/A of coefficients in the equation of state. Nonlinear diffraction theory is considered. Keywords include: ultrasonic nonlinearity, third-order elastic constants, schlieren optics, and fluoroperoskites.
