Available in PDF, EPUB and Kindle. Book excerpt: X-RADIOGRAPHIC, PENETRANT, ULTRASONIC, EDDY CURRENT, HOLOGRAPHIC, AND ACOUSTIC EMISSION TECHNIQUES WERE OPTIMIZED AND APPLIED TO THE EVALUATION OF 2219-T87 ALUMINUM ALLOY TEST SPECIMENS. ONE HUNDRED EIGHTEEN SPECIMENS CONTAINING A TOTAL OF 328 FATIGUE CRACKS WERE EVALUATED. THE CRACKS RANGED IN LENGTH FROM 0.500 INCH (1.27 CM) TO 0.007 INCH (0.018 CM) AND IN DEPTH FROM 0.178 INCH (0.451 CM) AND 0.001 INCH (0.003 CM). SPECIMEN THICKNESSES WERE NOMINALLY 0.060 INCH (0.152 CM) AND 0.210 INCH (0.532 CM) AND SURFACE FINISHES WERE NOMINALLY 32 AND 125 RMS AND 64 AND 200 RMS RESPECTIVELY. SPECIMENS WERE EVALUATED IN THE 'AS-MILLED' SURFACE CONDITION, IN THE CHEMICALLY MILLED SURFACE CONDITION AND, AFTER PROOF LOADING, IN A RANDOMIZED INSPECTION SEQUENCE. RESULTS OF THE NONDESTRUCTIVE TEST (NDT) EVALUATIONS WERE COMPARED WITH ACTUAL CRACK SIZE OBTAINED BY MEASUREMENT OF THE FRACTURED SPECIMENS. INSPECTION DATA WERE THEN ANALYZED TO PROVIDE A STATISTICAL BASIS FOR DETERMINING THE THRESHOLD CRACK DETECTION SENSITIVITY (THE LARGEST CRACK SIZE THAT WOULD BE MISSED) FOR EACH OF THE INSPECTION TECHNIQUES AT A 95% PROBABILITY AND 95% CONFIDENCE LEVEL.

Available in PDF, EPUB and Kindle. Book excerpt: Non-destructive evaluation (NDE) methods have dominated most of the fields of applied research and technology over the last twenty years. These techniques provide information on the functional efficiency of materials and structures without causing any structural impact on the structure itself. Their use enables the monitoring of the structural integrity, the structural condition as well as the service in-duced degradation of materials and structures during their service life. In this respect, they address a vast field of applications ranging from the aerospace and automotive industry to civil engineering structures and material quality control. This volume comprises scientific papers presented during the Fifth Conference on Emerging Technologies in Non-Destructive Testing (Ioannina, Greece, 19–21 September 2011). A broad spectrum of related research was presented during the course of the conference, including optical, acoustic, thermal, electrical and electromagnetic methods together with imaging tomographic and signal processing techniques. Special attention was given to NDE for Civil Engineering Structures and for the first time in the conference series, a multiple session on NDE for the protection of cultural heritage was organized. Emerging Technologies in Non-Destructive Testing V contains contributions by experts in this field from 22 different countries worldwide. Reflecting the stateof-the-art in Non-Destructive Evaluation, the book will prove to be a valuable companion to students, engineers and industrial partners who are active in the field of non-destructive evaluation and testing. This volume will also provide students and researchers with insight into the focal points of contemporary research efforts in the field of non-destructive evaluation.

Download or read book A Beginners Guide to Scanning Electron Microscopy written by Anwar Ul-Hamid and published by Springer. This book was released on 2018-10-26 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was developed with the goal of providing an easily understood text for those users of the scanning electron microscope (SEM) who have little or no background in the area. The SEM is routinely used to study the surface structure and chemistry of a wide range of biological and synthetic materials at the micrometer to nanometer scale. Ease-of-use, typically facile sample preparation, and straightforward image interpretation, combined with high resolution, high depth of field, and the ability to undertake microchemical and crystallographic analysis, has made scanning electron microscopy one of the most powerful and versatile techniques for characterization today. Indeed, the SEM is a vital tool for the characterization of nanostructured materials and the development of nanotechnology. However, its wide use by professionals with diverse technical backgrounds—including life science, materials science, engineering, forensics, mineralogy, etc., and in various sectors of government, industry, and academia—emphasizes the need for an introductory text providing the basics of effective SEM imaging.A Beginners’ Guide to Scanning Electron Microscopy explains instrumentation, operation, image interpretation and sample preparation in a wide ranging yet succinct and practical text, treating the essential theory of specimen-beam interaction and image formation in a manner that can be effortlessly comprehended by the novice SEM user. This book provides a concise and accessible introduction to the essentials of SEM includes a large number of illustrations specifically chosen to aid readers' understanding of key concepts highlights recent advances in instrumentation, imaging and sample preparation techniques offers examples drawn from a variety of applications that appeal to professionals from diverse backgrounds.

This book was released on 2012-09-14 with total page 1231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Condition assessment and characterization of materials and structures by means of nondestructive testing (NDT) methods is a priority need around the world to meet the challenges associated with the durability, maintenance, rehabilitation, retrofitting, renewal and health monitoring of new and existing infrastructures including historic monuments. Numerous NDT methods that make use of certain components of the electromagnetic and acoustic spectrum are currently in use to this effect with various levels of success and there is an intensive worldwide research effort aimed at improving the existing methods and developing new ones. The knowledge and information compiled in this book captures the current state of the art in NDT methods and their application to civil and other engineering materials and structures. Critical reviews and advanced interdisciplinary discussions by world-renowned researchers point to the capabilities and limitations of the currently used NDT methods and shed light on current and future research directions to overcome the challenges in their development and practical use. In this respect, the contents of this book will equally benefit practicing engineers and researchers who take part in characterization, assessment and health monitoring of materials and structures.

Download or read book Electromagnetic Nondestructive Evaluation XVI written by J.M.A. Rebello and published by IOS Press. This book was released on 2013-12-18 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electromagnetic Nondestructive Evaluation (ENDE) is the process of inducing electric currents, magnetic fields or both within a test object to assess its condition by observing the electromagnetic response. An important tool in fields as diverse as engineering, medicine and art, it does not permanently alter the object being tested, thus proving invaluable for product evaluation, troubleshooting and research. This book presents the proceedings of the 17th International Workshop on Electromagnetic Nondestructive Evaluation (ENDE), held in Rio de Janeiro, Brazil, in July 2012. ENDE workshop is an important event for all scientists with interests in non-destructive testing. The first workshop took place in 1995 in London UK, and has been followed by workshops held in various parts of the world, but this is the first time this workshop series has come to a Latin American country. The workshops bring together scientists and engineers active in research, development and industrial applications of ENDE. The book is divided into five sections: advanced sensors; analytical and numerical modeling; systems and techniques for electromagnetic NDE; characterization of materials and NDE of cracks; and new developments and others. Each section includes papers on a variety of subjects. From the papers submitted for publication, thirty six peer reviewed articles have been accepted, six of which emanate from Latin American authors. The book will be of interest to all those wishing to keep abreast of developments in the field, or who rely on the advanced techniques based on electromagnetic principles applied to nondestructive evaluation in their work.
