This book was released on 2014-04-23 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main goal of the book is a coherent treatment of the theory of propagation in materials of nonlinearly elastic waves of displacements, which corresponds to one modern line of development of the nonlinear theory of elastic waves. The book is divided on five basic parts: the necessary information on waves and materials; the necessary information on nonlinear theory of elasticity and elastic materials; analysis of one-dimensional nonlinear elastic waves of displacement – longitudinal, vertically and horizontally polarized transverse plane nonlinear elastic waves of displacement; analysis of one-dimensional nonlinear elastic waves of displacement – cylindrical and torsional nonlinear elastic waves of displacement; analysis of two-dimensional nonlinear elastic waves of displacement – Rayleigh and Love nonlinear elastic surface waves. The book is addressed first of all to people working in solid mechanics – from the students at an advanced undergraduate and graduate level to the scientists, professionally interesting in waves. But mechanics is understood in the broad sense, when it includes mechanical and other engineering, material science, applied mathematics and physics and so forth. The genesis of this book can be found in author’s years of research and teaching while a head of department at SP Timoshenko Institute of Mechanics (National Academy of Sciences of Ukraine), a member of Center for Micro and Nanomechanics at Engineering School of University of Aberdeen (Scotland) and a professor at Physical-Mathematical Faculty of National Technical University of Ukraine “KPI”. The book comprises 11 chapters. Each chapter is complemented by exercises, which can be used for the next development of the theory of nonlinear waves.

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 Dynamics of Pre Strained Bi Material Elastic Systems written by Surkay D. Akbarov and published by Springer. This book was released on 2015-02-11 with total page 1018 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with dynamics of pre-stressed or pre-strained bi-material elastic systems consisting of stack of pre-stressed layers, stack of pre-stressed layers and pre-stressed half space (or half plane), stack of pre-stressed layers as well as absolute rigid foundation, pre-stressed compound solid and hollow cylinders and pre-stressed sandwich hollow cylinders. The problems considered in the book relate to the dynamics of a moving and oscillating moving load, forced vibration caused by linearly located or point located time-harmonic forces acting to the foregoing systems. Moreover, a considerable part of the book relate to the problems regarding the near surface, torsional and axisymmetric longitudinal waves propagation and dispersion in the noted above bi-material elastic systems. The book carries out the investigations within the framework of the piecewise homogeneous body model with the use of the Three-Dimensional Linearized Theory of Elastic Waves in Initially Stressed Bodies.

This book was released on 2013-06-29 with total page 1790 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume (Parts A and B) contains the edited papers presented at the annual Review of Progress in Quan?itative Nondestructive Evalua tion held at the University of California (San Diego) in LaJo11a, August 3-8, 1986. The Review was organized and sponsored by the Center for NDE at Iowa State University and the Ames Laboratory, in cooperation with the Office of Basic Energy Sciences, USDOE, and the Materia1s Laboratory at Wright-Patterson Air Force Base. Approximately 400 attendees, a new record, representing various government agencies, industry, and universities participated in the technical presentations, poster sessions, and discussions. This Review, with its wide-ranging interchange of technical information, stands as one of the most compre hensive in the field of NDE research and engineering. In order to present the reader with a more usefu1 document, we have organized the symposium papers in these Proceedings by subject rather than by the order of presentation at the Review. Topical subject headings have been selected under which the 1arge majority of papers wou1d reasonably falI. Here, again, we have revised the format used in former years to accommodate an evolving focus of interest in the field. These categories cover a broad spectrum of research in NDE and encompass activities from fundamental work to early engineering applications. In the following paragraphs we offer a brief summary of the research presented in these Proceedings.

Download or read book Ultrasonic Testing of Materials written by Josef Krautkrämer and published by Springer Science & Business Media. This book was released on 2013-12-18 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second English edition is based on the third German edition. In view of most recent technological advances it has become necessary in many instances to supplement the second German edition and to revise some parts completely. In addition to piezo-electric methods, others are now also extensively discussed in Chapter 8. As for the intensity method, ultrasonic holo graphy is treated in the new Section 9. 4. In Part B, for reasons of syste matics, the resonance method has been included under transit-time methods. It appeared necessary to elaborate in greater detail the defini tion of the properties of pulse-echo testing equipment and their measure ments (10. 4). The more recent findings of pulse spectroscopy (5. 6) and sound-emission analysis (12) are mentioned only in passing because their significance is still controversial. Apart from numerous additions, particularly those concerning automatic testing installations, Part C also contains a new chapter which deals with tests on nuclear reactors (28), as well as a brief discussion of surface-hardness tests (32. 4). It became impossible to include a critical analysis of the principal standards in Chapter 33. A few are mentioned, however, where the most important subjects (e. g. , the testing of welded joints in Chapter 26) are discussed, while others are only tabulated in Chapter 33. The present, vastly increased literature made bibliographical selection rather difficult. Consequently, we wish to apologize to any authors whose reports may have been omitted because of limitations governing the size of this volume.

This book was released on 2012-12-06 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the Solid Mechanics Program at the Office of Naval Research (ONR), our primary mission is to establish a basic research program which addresses the funda mental issues in solid mechanics where a clear scientific understanding is lacking. Our approach involves first identifying the various scales at which material and structural response and failure occur. Within each level of behavior we address the basic mechanical phenomena for which a clear physical description is not available. ONR's program emphasizes experimental research to identify and quantify the interacting behavior and response mechanisms. Theoretical and computational approaches are developed to explain the details of the physical processes and to establish the technology necessary to control the thermomechanical behavior of materials and structures. Within the Department of Defense, it is a natural evolution that all new systems must generally operate in more demanding environments than the systems they replace. Thus, structural designers are pushed towards lighter weight, precision structures utilizing new materials. In such an environment, structural design mar gins simultaneously shrink and become more critical. Such trends make it essential that a well founded scientific base for the nondestructive detection and assessment of subcritical flaws in structural materials and structures exist. Within the ONR Solid Mechanics Program we are interested in both the identification of flaws and assessment of their degree of criticality.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers presented at the Seventh International Symposium on Acoustical Imaging and Holography. The meeting was held in Chicago, Illinois U.S.A. on August 30 - September 1, 1976. Since 1967 this series of conferences has served as an international forum for bringing together the many different facets of the ultrasonic visualization field. Medical diagnosis, nondestructive testing, underwater viewing, seismic the mapping, and acoustic analytical microscopy are examples of broad range applications of this technology. Throughly broad in scope, the common denominator that binds this volume together is the application of engineering and physics disciplines to the creation of images by means of ultrasonic waves.

Download or read book EMATs for Science and Industry written by Masahiko Hirao and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: EMATs for Science and Industry comprises the physical principles of electromagnetic acoustic transducers (EMATs) and the applications to scientific and industrial ultrasonic measurements on materials. The text is arranged in four parts: -PART I is intended to be a self-contained description of the basic elements of coupling mechanism along with practical designing of EMATs for various purposes. There are several implementations to compensate for the low transfer efficiency of the EMATs. Useful tips to make an EMAT are also presented. -PART II describes the principle of electromagnetic acoustic resonance (EMAR), which makes the most of contactless nature of EMATs and is the most successful amplification mechanism for precise velocity and attenuation measurements. -PART III applies EMAR to studying the physical acoustics. New measurements emerged on three major subjects; in situ monitoring of dislocation behavior, determination of anisotropic elastic constants, and acoustic nonlinearity evolution. -PART IV deals with a variety of individual topics encountered in industrial applications, for which the EMATs are believed to the best solutions.
