Download or read book Acoustics of Solids written by Abraham I. Beltzer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technological developments in composite materials, non-destructive testing, and signal processing as well as biomedical applications, have stimulated wide-ranging engineering investigations of heterogeneous, anisotropic media and surface waves of different types. Wave propagation in solids is now of considerable importance in a variety of applications. The book presents many of the key results in this field and interprets them from a unified engineering viewpoint. The conceptual importance and relevance for applications were the prevailing criteria in selecting the topics. Included are body and surface waves in elastic, viscoelastic, and piezoelectric media and waveguides, with emphasis on the effects of inhomogeneity and anisotropy. The book differs in many aspects from the other monographs dealing with wave propagation in solids. It focuses on physically meaningful theoretical models, a broad spectrum of which is covered, and not on mathematical techniques. Some of the results, particularly those dealing with waves in composites, are given for the first time in the monographical literature. Both, exact and approximate approaches, are discussed. While the subject is advanced, the presentation is at an intermediate level of mathematical complexity, making understanding easier.

Download or read book Acoustic Invisibility for Elliptic Objects written by Davide Enrico Quadrelli and published by Springer Nature. This book was released on 2023-01-30 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book investigates acoustic cloaking for elliptical targets, starting from the development of a systematic approach to deal with such non-axisymmetrical shapes by adopting transformation acoustics in elliptic coordinates, and concluding with numerical and experimental validation of a microstructured cloak in the underwater environment. The book thus comprises all the steps from theory to practice that led to the first experimental validation of acoustic invisibility for non-cylindrical objects, whose results are presented in the last chapter. Indeed, despite Transformation Theory is now an established tool to design material distributions capable to unlock the design of invisibility devices, it is not trivial to apply it for shapes different than the sphere and the cylinder, which are thus the ones mainly addressed in the literature. This book paves the way for exploration of other shapes, demonstrating the effectiveness of a pentamode cloak in reducing the acoustic visibility of an elliptical target, and discussing design choices that can make the implementation of the required microstructure less cumbersome despite the lack of axial symmetry of the problem, from both the numerical and manufacturing point of views.

Book excerpt: Physical Acoustics: Principles and Methods reviews the principles and methods of physical acoustics and covers topics ranging from third sound in superfluid helium films to the method of matched asymptotic expansions (MAE). Ultrasonic diffraction from single apertures and its application to pulse measurements and crystal physics are also discussed, together with elastic surface wave devices, acoustic emission, and nonlinear effects in piezoelectric quartz crystals. Comprised of six chapters, this volume begins with a detailed treatment of the theory of third sound in superfluid helium films, third sound resonators, and many other properties. The second chapter is devoted to the MAE method, with emphasis on its ability to produce results in acoustics and to provide insight into classical problems. Subsequent chapters deal with bulk and surface waves; phase coded signals and their generation and detection by interdigital grid structures; elastic surface wave devices such as pulse compression filters; and nonlinear effects in quartz crystals. The final chapter describes acoustic emission and the noise produced in materials when they are strained. This book will be of interest to physicists.

Download or read book Physical Acoustics V14 written by Warren P. Mason and published by Elsevier. This book was released on 2012-12-02 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical Acoustics: Principles and Methods, Volume XIV is a five-chapter text that covers significant studies on acoustic microscopy, sound propagation in liquid crystals, ultrasonic transducers, and ultrasonic flowmeters. The opening chapter discusses techniques of acoustic microscopy, aberration and resolution performance, acoustic lens transfer functions, antireflection coatings, and both transmission and reflection acoustic microscopy. The following chapter deals with the applications to the states called liquid crystals or anisotropic liquids, states in which the material flows but yet has a long-range order that makes it macroscopically anisotropic. The third chapter focuses on the principles and practical applications of electromagnetic transducers for both surface waves and bulk waves. The fourth chapter surveys first the characterization of ultrasonic transducers for materials testing and then compares actual responses to those of an ""ideal"" transducer, elaborating on the many important factors that affect the results obtained with an ultrasonic testing system. The final chapter explains the principles underlying ultrasonic measurements of flow, specifically covering eight different categories of ultrasonic flow measurement principles and their industrial applications indicated. This book will be of great value to researchers in their fields of electronics technology and applied and engineering mechanics.

Download or read book Acoustic Waves in Periodic Structures Metamaterials and Porous Media written by Noé Jiménez and published by Springer Nature. This book was released on 2021-11-03 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book delivers a comprehensive and up-to-date treatment of practical applications of metamaterials, structured media, and conventional porous materials. With increasing levels of urbanization, a growing demand for motorized transport, and inefficient urban planning, environmental noise exposure is rapidly becoming a pressing societal and health concern. Phononic and sonic crystals, acoustic metamaterials, and metasurfaces can revolutionize noise and vibration control and, in many cases, replace traditional porous materials for these applications. In this collection of contributed chapters, a group of international researchers reviews the essentials of acoustic wave propagation in metamaterials and porous absorbers with viscothermal losses, as well as the most recent advances in the design of acoustic metamaterial absorbers. The book features a detailed theoretical introduction describing commonly used modelling techniques such as plane wave expansion, multiple scattering theory, and the transfer matrix method. The following chapters give a detailed consideration of acoustic wave propagation in viscothermal fluids and porous media, and the extension of this theory to non-local models for fluid saturated metamaterials, along with a description of the relevant numerical methods. Finally, the book reviews a range of practical industrial applications, making it especially attractive as a white book targeted at the building, automotive, and aeronautic industries.

Download or read book Surface Waves in Anisotropic and Laminated Bodies and Defects Detection written by Robert V. Goldstein and published by Springer Science & Business Media. This book was released on 2006-02-21 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the variety of wave motions one can single out surface wave pr- agation since these surface waves often adjust the features of the energy transfer in the continuum (system), its deformation and fracture. Predicted by Rayleigh in 1885, surface waves represent waves localized in the vicinity ofextendedboundaries(surfaces)of?uidsorelasticmedia. Intheidealcase of an isotropic elastic half-space while the Rayleigh waves propagate along the surface, the wave amplitude (displacement) in the transverse direction exponentially decays with increasing distance away from the surface. As a resulttheenergyofsurfaceperturbationsislocalizedbytheRayleighwaves within a relatively narrow layer beneath the surface. It is this property of the surface waves that leads to the resonance phenomena that accompany the motion of the perturbation sources (like surface loads) with velocities close to the Rayleigh one; (see e. g. , R. V. Goldstein. Rayleigh waves and resonance phenomena in elastic bodies. Journal of Applied Mathematics and Mechanics (PMM), 1965, v. 29, N 3, pp. 608-619). It is essential to note that resonance phenomena are also inherent to the elastic medium in the case where initially there are no free (unloaded) surfaces. However, they occur as a result of an external action accompanied by the violation of the continuity of certain physical quantities, e. g. , by crack nucleation and dynamic propagation. Note that the aforementioned resonance phenomena are related to the nature of the surface waves as homogeneous solutions (eigenfunctions) of the dynamic elasticity equations for a half-space (i. e. nonzero solutions at vanishing boundary conditions).

Download or read book Dissipative Ordered Fluids written by André M. Sonnet and published by Springer Science & Business Media. This book was released on 2012-01-24 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a book on the dissipative dynamics of ordered fluids, with a particular focus on liquid crystals. It covers a whole range of different theories, mainly concerned with nematic liquid crystals in both their chiral and nonchiral variants. The authors begin by giving a detailed account of the molecular origins of orientational order in fluids. They then go on to develop a general framework in which continuum theories for ordered fluids can be phrased. Within this unified setting, they cover both well-established classical theories and new ones with aspects that are not yet completely settled. The book treats a wide range of hydrodynamic theories for liquid crystals, from the original 1960s works by Ericksen and Leslie to new, fast-developing ideas of liquid crystal science. The final chapter is devoted to nematoacoustics and its applications. Old experiments on the propagation of ultrasound waves in nematic liquid crystals are interpreted and explained in the light of a new theory developed within the general theoretical infrastructure proposed in the body of the book. This book is intended both for graduate students and professional scholars in mathematics, physics, and engineering of advanced materials. It delivers a solid framework for liquid crystal hydrodynamics and shows the unifying concepts at the basis of the classical theories. It illustrates how these concepts can also be applied to a wide variety of modern topics. Andre M. Sonnet is in the Department of Mathematics and Statistics at the University of Strathclyde, Glasgow (Scotland) and Epifanio G. Virga is in the Department of Mathematics at the University of Pavia (Italy). They have a long history of working together in liquid crystal science and have contributed, in particular, to the theories of defects and biaxial nematics.

Download or read book Nonequilibrium Phonon Dynamics written by Walter E. Bron and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phonons are always present in the solid state even at an absolute temperature of 0 K where zero point vibrations still abound. Moreover, phonons interact with all other excitations of the solid state and, thereby, influence most of its properties. Historically experimental information on phonon transport came from measurements of thermal conductivity. Over the past two decades much more, and much more detailed, information on phonon transport and on many of the inherent phonon interaction processes have come to light from experiments which use nonequilibrium phonons to study their dynamics. The resultant research field has most recently blossomed with the development of ever more sophisticated experimental and theoretical methods which can be applied to it. In fact, the field is moving so rapidly that new members of the research community have difficulties in keeping up to date. This NATO Advanced Study Institute (ASI) was organized with the objective of overcoming the information barrier between those expert in the field and those who are new to it. Thus it was decided to (i) organize a set of tutorially based lectures covering most of the important facets in the field, and (ii) to produce an Institute proceedings which would serve both as the first general textbook, as well as a valuable reference book, for this field of knowledge.
