Nonlinear Acoustics( Book )

3 editions published between 1984 and 1987 in English and held by 3 WorldCat member libraries worldwide

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

Studies of Linear and Nonlinear Ultrasonic Phenomena( Book )

1 edition published in 1978 in English and held by 1 WorldCat member library worldwide

The technical report is divided into three parts: Part I. Ultrasonic wave velocity and attenuation are measured in the critical mixing region of the binary liquid mixture hexane and beta, beta'-dichloroethyl ether. The results are compared with results in other binary liquid mixtures. Part II. Comparison of the measurement of ultrasonic pressure amplitudes by four different techniques and measurement of ultrasonic wave velocity in solids by use of capacitive transducers. Part III. Nonlinear acoustics of solids is discussed. Nonlinearity parameters of germanium, fused silica, and copper are measured, and their temperature dependence is determined between 3 K and 300 K. (Author)
Ultrasonic Wave Generation and Propagation( Book )

1 edition published in 1971 in English and held by 1 WorldCat member library worldwide

The report covers four topics: (1) In 'Simplification of Apparatus to Diffract Light by Ultrasonic Waves, ' it is shown that the laser is ideally suited to such measurements because the laser beam is small, intense, and collimated, each of which simplifies measurements. (2) The next three chapters deal with various aspects of ultrasonic parametric oscillations, including the nonlinear equation which probably describes the situation. The use of parametric oscillations to make a variable frequency transducer has not been practical. On the other hand, measurement of the threshold of parametric oscillation does offer promise of a means of measuring relative attenuation. (3) Diffraction lobes from the beam pattern of transducers can be eliminated quite simply in certain cases. This technique is described in Chapters V and VI. The analogous techniques in optics is referred to as 'apodization.' Therefore, it would be correct to refer to this ultrasonic technique as 'apodization of transducers.' The final chapter shows the way the apodized transducers can be used to make a detailed study of the energy redistribution in an ultrasonic beam reflected from a liquid-solid interface at the angle at which surface waves are generated.

A study of the ultrasonic spectrum in a resonant cavity( Book )

1 edition published in 1967 in English and held by 1 WorldCat member library worldwide

A spectrum analyzer is used to examine the ultrasonic spectra produced when large amplitude ultrasonic waves are caused to resonate in a water-filled cavity. The cavity, consisting of a plane transducer and concave reflector, produces frequency components which appear to be the result of beating (a linear process) and/or modulation (a non-linear process). A scheme for labelling the frequency components is developed. (Author)

Theory of Harmonic Generation of Finite Amplitude Ultrasonic Waves in Solids of Hexagonal Symmetry( Book )

1 edition published in 1984 in English and held by 1 WorldCat member library worldwide

The Technical Report gives a complete analysis of the theory of propagation of a finite amplitude ultrasonic wave in a nonlinear crystal of hexagonal symmetry along the symmetry axis and along any direction in the basal plane. From the theory we conclude that at least four of the ten third order elastic constants can be evaluated from harmonic generation measurements in the appropriate directions in hexagonal crystals
Rayleigh Reflections and Nonlinear Acoustics of Solids( Book )

1 edition published in 1980 in English and held by 1 WorldCat member library worldwide

Part I. Schlieren Studies of Ultrasonic Waves, and Part II. Nonlinear Acoustics of Solids. Part I. The report begins with the description of a unique goniometer for use in a schlieren system for visualization of ultrasonic waves in liquids. By using the properties of parallelograms we were able to produce a precision goniometer without use of precision machine shop facilities. The goniometer is used to obtain schlieren photographs of leaky Rayleigh waves excited on an Al2O3 layer on a stainless steel reflector immersed in water, showing that the Rayleigh wave velocity in this case is less than that of either a water-Al2O3 layer or a water-stainless steel layer. Part II. Four subjects are covered: (1) the Nonlinearity Parameters and Third-Order Elastic Constants of Copper between 300 and 3 K; (2) Measurement of Nonlinearity Parameters in Small Solid Samples by the Harmonic Generation Technique; (3) Relationship between Solid Nonlinearity Parameters and Thermodynamic Gruneisen Parameters; and (4) Quantum Mechanical Theory of Nonlinear Interaction of Ultrasonic Waves
Ultrasonic Wave Reflection at Liquid-Solid Interfaces( Book )

1 edition published in 1978 in English and held by 1 WorldCat member library worldwide

This technical report comprises ten publications on the reflection of ultrasonic waves at liquid-solid interfaces. Description is given of both experimental and theoretical advances in the understanding and utilization of reflection phenomena. Attention is concentrated primarily on the angles at which leaky surface waves are excited along the interface. Rayleigh angle phenomena are described, as well as the backward shift resulting from a periodicity superimposed on the interface. Utilization of these phenomena in nondestructive evaluation and in underwater acoustics is mentioned
Ultrasonic studies of the nonlinear properties of solids( Book )

1 edition published in 1972 in English and held by 1 WorldCat member library worldwide

WHEN ONE EXCITES A SINUSOIDAL ULTRASONIC WAVE OF FINITE AMPLITUDE, THE NONLINEAR PROPERTIES OF THE PROPAGATING MEDIUM PRODUCE WAVEFORM DISTORTION. SUCH WAVEFORM DISTORTION, WHICH OCCURS IN GAS AND LIQUIDS, HAS RECENTLY BEEN OBSERVED IN SOLIDS. THE MATHEMATICAL DESCRIPTION OF THIS PHENOMENON IS COMPLICATED BY THE FACT THAT ONE CAN NO LONGER USE THE HOOKE'S LAW APPROXIMATION. FORTUNATELY THE MATHEMATICAL DESCRIPTION OF ISOTROPIC MATERIALS AND CUBIC CRYSTALS CAN BE MADE USING RELATIVELY STRAIGHTFORWARD NONLINEAR DIFFERENTIAL EQUATIONS IN WHICH THIRD ORDER ELASTIC CONSTANTS PLAY A SIGNIFICANT ROLE. RECENT EXPERIMENTS DEMONSTRATE THE FACTS THAT (1) THE SECOND HARMONIC IN THE DISTORTED WAVE IS PROPORTIONAL TO THE DISTANCE TRAVELLED AND TO THE SQUARE OF THE FREQUENCY, (2) THE THIRD HARMONIC IS PROPORTIONAL TO THE SQUARE OF THE DISTANCE TRAVELLED AND THE CUBE OF THE FREQUENCY, (3) INTERFERENCE AMONG THE HARMONIC COMPONENTS CAN PRODUCE UNUSUALLY LARGE SIGNALS. USING A CAPACITIVE DETECTOR IT IS POSSIBLE TO MEASURE AMPLITUDES OF THE FUNDAMENTAL, THE SECOND HARMONIC, AND THE THIRD HARMONIC AS SMALL AS 10 TO THE MINUS 4 A. FROM THESE MEASUREMENTS THE THIRD ORDER ELASTIC CONSTANTS AND THEIR TEMPERATURE DEPENDENCE CAN BE DETERMINED. FINITE AMPLITUDE DISTORTION SHOULD BE MOST USEFUL FOR NONDESTRUCTIVE TESTING OF EXTREMELY PURE AND UNIFORM SAMPLES

Theory of the Propagation of Finite Amplitude Ultrasonic Waves in Pure Mode Directions in Hexagonal and Trigonal Crystals( Book )

1 edition published in 1985 in English and held by 1 WorldCat member library worldwide

The nonlinear theory describing the propagation of finite amplitude ultrasonic waves in pure mode directions in hexagonal and trigonal crystals is developed. By evaluating the coefficient of the term which couples the longitudinal wave of finite amplitude to the transverse modes, one finds the pure mode directions by requiring this coefficient to vanish. The result is that for hexagonal crystals the directions along the symmetry axis and in the basal plane are pure longitudinal mode directions. Pure mode directions are also found for longitudinal waves propagating tangential to a cone whose apex is centered about the symmetry axis and whose apex angle is a function of the second-order elastic constants of the sample under consideration. The third-order elastic constants which determine the magnitude of the second harmonic of an initially sinusoidal ultrasonic wave are evaluated for these additional directions. For finite amplitude longitudinal ultrasonic waves in trigonal crystals we have specialized to nonpiezoelectric crystals and have evaluated the third-order elastic constants which determine the magnitude of the second harmonic of an initially sinusoidal wave propagating in the following pure mode directions: (1) along the symmetry axis (the c-direction); (2) along the a-direction in the basal plane; (3) along the direction in the basal plane that makes an angle of 60 deg with the a-direction; and (4) along a direction in the b-c plane whose angle with respect to the b-axis is a function of the second-order elastic constants of the crystal under consideration. Keywords: Ultrasonic harmonic generation; Nonlinear hexagonal and trigonal crystals
