Download or read book Electromagnetic Acoustic Transducers written by Masahiko Hirao and published by Springer. This book was released on 2016-10-25 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition provides comprehensive information on electromagnetic acoustic transducers (EMATs), from the theory and physical principles of EMATs to the construction of systems and their applications to scientific and industrial ultrasonic measurements on materials. The original version has been complemented with selected ideas on ultrasonic measurement that have emerged since the first edition was released. The book is divided into four parts: PART I offers a self-contained description of the basic elements of coupling mechanisms along with the practical designing of EMATs for various purposes. Several implementations to compensate for EMATs’ low transfer efficiency are provided, along with useful tips on how to make an EMAT. PART II describes the principle of electromagnetic acoustic resonance (EMAR), which makes the most of EMATs’ contactless nature and is the most successful amplification mechanism for precise measurements of velocity and attenuation. PART III applies EMAR to studying physical acoustics. New measurements have emerged with regard to four major subjects: in situ monitoring of dislocation behavior, determination of anisotropic elastic constants, pointwise elasticity mapping (RUM), and acoustic nonlinearity evolution. PART IV deals with a variety of individual issues encountered in industrial applications, for which the EMATs are believed to be the best solutions. This is proven by a number of field applications.

Download or read book Theory and Methodology of Electromagnetic Ultrasonic Guided Wave Imaging written by Songling Huang and published by Springer. This book was released on 2019-06-29 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by respected experts, this book highlights the latest findings on the electromagnetic ultrasonic guided wave (UGW) imaging method. It introduces main topics as the Time of Flight (TOF) extraction method for the guided wave signal, tomography and scattering imaging methods which can be used to improve the imaging accuracy of defects. Further, it offers essential insights into how electromagnetic UGW can be used in nondestructive testing (NDT) and defect imaging. As such, the book provides valuable information, useful methods and practical experiments that will benefit researchers, scientists and engineers in the field of NDT.

Download or read book Electromagnetic Acoustic Transducer Analysis written by Reza Jafari and published by LAP Lambert Academic Publishing. This book was released on 2011-10 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electromagnetic acoustic transducers (EMATs) are non-contact, non-destructive testing devices for conducting specimens. The efficiency of EMATs is inherently low and methods for increasing it have been the subject of intense research. In publications, the finite element (FE) technique has been applied to the diffusion equation in order to model EMATs. However, electromagnetic theory indicates that the diffusion equation must be solved for the magnetic vector potential (MVP) in conjunction with an equation for the total current. An existing FE formulation considering the two equations becomes unstable when modeling transient inputs in EMAT transmitters. The limitation posed by the instability prompted the development of an improved FE formulation, which solves the two equations and is suitable for the modeling of EMATs.The objective of the research work described in this thesis is to properly and accurately model EMATs, so that their efficiency could be improved at the design stage. The thesis describes the governing equations of EMATs, improved techniques for their solution, and the application of these techniques to the analysis of such devices.

Download or read book Electromagnetic Nondestructive Evaluation XIX written by N. Yusa and published by IOS Press. This book was released on 2016-06-09 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: There have been many developments in the field of electromagnetic nondestructive evaluation in recent years, and it has become an increasingly valuable tool in many areas of industry, engineering and construction. This book presents selected papers from the 20th International workshop on Electromagnetic Nondestructive Evaluation (ENDE) held in Sendai, Japan, in September 2015. ENDE workshops aim to provide an international forum for discussion on the state-of-the-art and perspectives in the field of electromagnetic nondestructive methods from the point of view of science and technology, as well as their applications in industry and engineering, which have contributed to the development of nondestructive testing and evaluation techniques using electromagnetic fields. The book will be of interest to all those whose work involves the use or development of electromagnetic nondestructive evaluation techniques, in whatever field.

Download or read book Advanced Ultrasonic Methods for Material and Structure Inspection written by Tribikram Kundu and published by John Wiley & Sons. This book was released on 2013-03-01 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrasonic signals are increasingly being used for predicting material behavior, both in an engineering context (detecting anomalies in a variety of structures) and a biological context (examining human bones, body parts and unborn fetuses). Featuring contributions from authors who are specialists in their subject area, this book presents new developments in ultrasonic research in both these areas, including ultrasonic NDE and other areas which go beyond traditional imaging techniques of internal defects. As such, both those in the biological and physical science communities will find this an informative and stimulating read.

Book excerpt: This report is a brief review of those aspects of electromagnetic-acoustic generation and detection of interest in nondestructive evaluation (NDE). Since this is a developing technology, there are no standard transducer designs and practices. The principles of ultrasonic wave generation as related to electromagnetic-acoustic transducer (EMAT) design are emphasized. EMATs are of interest in NDE because they offer a completely noncontacting technique for generating and detecting ultrasonic waves. The report discusses theory, experimental studies, design, and applications of EMATs. (Author).
