This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the potential application of a technique called Material Characterization by Resonance Acoustic Spectroscopy (MCRAS) for the purpose of non-destructive evaluation (NDE) and on-line monitoring of inhomogeneous non-isotropic copper rods produced by the Ohno Continuous Casting (OCC) process. Experimental measurements of the scattered pressure fields are performed on copper samples with different levels of inhomogeneity by using the short-pulse Method of Isolation and Identification of Resonances (MIIR). Two distinct types of resonances have been observed from the experimental results. These resonances are proved to be useful in estimating the average material properties and grain sizes of the copper rods. It is concluded that MCRAS is a potentially powerful technique for non-destructive evaluation and on-line monitoring of inhomogeneous non-isotropic copper rods.

This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potential applications of resonance acoustic spectroscopy (RAS) for the purpose of nondestructive evaluation (NDE) and on-line monitoring of isotropic clad rods and transversely isotropic cylinders are investigated in this thesis. Mathematical models are developed for the scattering of an infinite plane acoustic wave from infinite elastic and viscoelastic clad rods and infinite transversely isotropic cylinders. In these mathematical models, the scattered pressure field is obtained in terms of normal-mode Rayleigh series. Experimental measurements of the scattered pressure fields of various cylindrical components are performed using the short-pulse method of isolation and identification of resonances (MIIR). The method is applied to: copper-clad aluminum rods, Epon-815-clad steel rods, and fiber reinforced composite rods. The experimental results show good consistency with the results obtained from mathematical models. It is concluded that RAS is a potentially powerful technique for nondestructive evaluation and on-line monitoring of various cylindrical components.

This book was released on 2018-10-19 with total page 761 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multi-contributed volume provides a practical, applications-focused introduction to nonlinear acoustical techniques for nondestructive evaluation. Compared to linear techniques, nonlinear acoustical/ultrasonic techniques are much more sensitive to micro-cracks and other types of small distributed damages. Most materials and structures exhibit nonlinear behavior due to the formation of dislocation and micro-cracks from fatigue or other types of repetitive loadings well before detectable macro-cracks are formed. Nondestructive evaluation (NDE) tools that have been developed based on nonlinear acoustical techniques are capable of providing early warnings about the possibility of structural failure before detectable macro-cracks are formed. This book presents the full range of nonlinear acoustical techniques used today for NDE. The expert chapters cover both theoretical and experimental aspects, but always with an eye towards applications. Unlike other titles currently available, which treat nonlinearity as a physics problem and focus on different analytical derivations, the present volume emphasizes NDE applications over detailed analytical derivations. The introductory chapter presents the fundamentals in a manner accessible to anyone with an undergraduate degree in Engineering or Physics and equips the reader with all of the necessary background to understand the remaining chapters. This self-contained volume will be a valuable reference to graduate students through practising researchers in Engineering, Materials Science, and Physics. Represents the first book on nonlinear acoustical techniques for NDE applications Emphasizes applications of nonlinear acoustical techniques Presents the fundamental physics and mathematics behind nonlinear acoustical phenomenon in a simple, easily understood manner Covers a variety of popular NDE techniques based on nonlinear acoustics in a single volume

Book excerpt: Scattering is the collision of two objects that results in a change of trajectory and energy. For example, in particle physics, such as electrons, photons, or neutrons are "scattered off" of a target specimen, resulting in a different energy and direction. In the field of electromagnetism, scattering is the random diffusion of electromagnetic radiation from air masses is an aid in the long-range sending of radio signals over geographic obstacles such as mountains. This type of scattering, applied to the field of acoustics, is the spreading of sound in many directions due to irregularities in the transmission medium. Volume I of Scattering will be devoted to basic theoretical ideas, approximation methods, numerical techniques and mathematical modeling. Volume II will be concerned with basic experimental techniques, technological practices, and comparisons with relevant theoretical work including seismology, medical applications, meteorological phenomena and astronomy. This reference will be used by researchers and graduate students in physics, applied physics, biophysics, chemical physics, medical physics, acoustics, geosciences, optics, mathematics, and engineering. This is the first encyclopedic-range work on the topic of scattering theory in quantum mechanics, elastodynamics, acoustics, and electromagnetics. It serves as a comprehensive interdisciplinary presentation of scattering and inverse scattering theory and applications in a wide range of scientific fields, with an emphasis, and details, up-to-date developments. Scattering also places an emphasis on the problems that are still in active current research. The first interdisciplinary reference source on scattering to gather all world expertise in this technique Covers the major aspects of scattering in a common language, helping to widening the knowledge of researchers across disciplines The list of editors, associate editors and contributors reads like an international Who's Who in the interdisciplinary field of scattering

This book was released on 2020-01-14 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional ultrasonic methods based on ultrasonic characteristics in the linear elastic region are mainly sensitive to mature defects but are much less responsive to micro-damage or incipient material degradation. Recently, nonlinear ultrasonic characteristics beyond the linear ultrasonic amplitude range have been studied as a method for overcoming this limitation, and hence, many researchers are engaged in theoretical, experimental, and various application studies. However, the nonlinear ultrasonic characteristics are quite exacting compared to the linear phenomena so that they require vast experience and high proficiency in order to obtain proper experimental data. Actually, many researchers, especially beginners including graduate students, have difficulty in reliably measuring nonlinear ultrasonic characteristics. This book provides key technological know-how from experts with years of experience in this field, which will help researchers and engineers to obtain a clear understanding and high quality data in the nonlinear ultrasonic experiments and applications.

This book was released on 2010-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative book provides a comprehensive review of the highly important subject of non-destructive evaluation of reinforced concrete structures. Engineers have a range of sophisticated techniques at their disposal to assess the condition of reinforced concrete structures that do not cause material damage and which usually enable the structure to be used while the surveys are carried out. Non-destructive evaluation of the infrastructure also plays a key role in calculating and prioritising where money should be spent on repair or replacement. Providing details of related techniques and case studies, this book offers an overview of how to plan and implement the NDT of reinforced concrete structures.
