Available in PDF, EPUB and Kindle. Book excerpt: Resonance Acoustic Spectroscopy deals with the analysis of waves generated in an elastic body by a plane harmonic acoustic wave. It is the first monograph to treat new analytical and experimental methods for the investigation of the excitation, propagation and re-radiation of elastic waves in solid, thick-walled and thin-walled elastic scatterers.The material is presented systematically, comprising the formulation of the problem, method of solution, algorithm, computation and analysis. A large number of computational results are given in the form of modal resonances, form functions, dispersion curves and acoustic spectrograms. Particular attention is paid to the interpretation of the solutions.

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.

Book excerpt: This report reports on work performed for the International Atomic Energy Agency (IAEA) through the Program Office for Technical Assistance (POTAS). In this work, we investigate possible applications of nondestructive acoustics measurements to facilitate IAEA safeguards at bulk processing facilities. Two different acoustic techniques for verifying the internal structure of a processing tank were investigated. During this effort we also examined two acoustic techniques for assessing the fill level within a processing tank. The fill-level measurements could be made highly portable and have an added safeguards advantage that they can also detect stratification of fill material. This later application may be particularly useful in confirming the absence of stratification in plutonium processing tanks before accountability samples are withdrawn.

Book excerpt: Objects resonate at specific frequencies when mechanically excited. The specific resonance frequencies are a function of shape, size, material of construction, and contents of the object. This paper discusses the use of acoustic resonance spectroscopy (ARS) to monitor containers and detect tampering. Evaluation of this technique is based on simulated storage simulations. Although these simulations show promise for this application of ARS, final evaluation will require actual field testing.

Download or read book Optoacoustic Spectroscopy and Detection written by Yoh-Han Pao and published by Elsevier. This book was released on 2012-12-02 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optoacoustic Spectroscopy and Detection discusses the fundamental principles and practice of optoacoustic spectroscopy. This book serves as a basis for evaluation of the feasibility of using such techniques in specific instances. Organized into eight chapters, this book starts with an overview of the detection and identification of gas contaminants, which is necessary to understand the physical description of the generation and measurement of the optoacoustic signal. This text then provides an understanding of the optoacoustic effect on a molecular scale and describes the energy transfer processes and estimates of the lifetimes of vibrationally excited states. Other chapters consider the options available to the researcher in the selection of optoacoustic system design. This book discusses as well the capabilities and limitations of various optoacoustic system designs. The final chapter deals with the technique used for exploring the absorption spectra of substances, including powders, gels, adsorbed films, and organic tissues. This book is a valuable resource for researchers and graduate students engaged in the study of optoacoustic spectroscopy.
