Authors: Krylov, Victor V.
Abstract: The book gives a brief account of the theory of radiation and scattering of sound in liquids and gases. General principles of radiation and scattering of acoustic waves are considered, including Huygens’ principle, the reciprocity theorem, the problem of the existence and uniqueness of solutions. Acoustic fields generated by some complicated radiators are analysed in detail. Basic definitions and facts relating to the scattering of sound by an infinite cylinder, sphere, gas bubbles in liquids, etc. are considered as well. Much of attention is paid to the general theory of scattering with respect to the scattering of acoustic waves. These include the method of boundary integral equations and the methods based on the approximate solutions of the equations of Lippmann - Schwinger type. Considered are also energy conservation issues at wave scattering and the problems linked to causality and Kramers - Kronig relations. The book is intended for students and researchers working in the field of acoustics. (Abstract translated from the Russian).

Authors: Krasil'nikov, V.A.; Krylov, Victor V.
Abstract: The book gives a concise account of physical acoustics – a branch of physics studying the interaction of acoustic waves with matter at the macro and microscopic levels. It starts with the basics of mechanics of continuum needed to analyse the problems of physical acoustics. This is followed by the description of linear and nonlinear problems of acoustics of gases, liquids and solids. Also considered are the problems of ‘turbulence and sound’, acoustics of magnetic media, and acoustics of crystals. Important information is provided also on acousto-electronics and acousto-optics. Some parts of the book are illustrated by description of the methodology of experiments and experimental data. The book would be of interest to undergraduate students of physical, chemical and engineering specialities, postgraduate students, researchers, lecturers, acoustic engineers, and all those engaged in fluid mechanics, elasticity, solid state physics, radio physics, signal processing, underwater acoustics and geophysics.

Abstract: To reduce the environmental impact (in terms of visibility and noise) it is desirable to construct inter-urban high-speed rail lines with small embankments. However, these small embankments tend to be flexible and on soft ground track-soil bending waves may result in significant transient train-induced soil deflections. These deflections in the permanent way could, in turn, have a major effect on ride quality and also on maintenance costs. A variable frequency inertial vibrator and a series of geophones have been used to examine the response of soil both with and without a rail. The measured soil responses have been used to predict soil model parameters, which are introduced into analytical models in order to predict bending waves in the track/embankment system. The consequent displacements are highly dependent on the speed of the train. This maximum deflection was also found to be dependent on the amount of damping in the system. For all reasonable assumptions the amount of damping present is insufficient to limit deflection to tolerable magnitudes. Thus, the theoretical models can indicate suitable restrictions on train speeds for particular track conditions.
