Available in PDF, EPUB and Kindle. Book excerpt: This thesis provides an innovative strategy for rail crack monitoring using the acoustic emission (AE) technique. The field study presented is a significant improvement on laboratory studies in the literature in terms of complex rail profile and crack conditions as well as high operational noise. AE waves induced by crack propagation, crack closure, wheel-rail impact and operational noise were obtained through a series of laboratory and field tests, and analyzed by wavelet transform (WT) and synchrosqueezed wavelet transform (SWT). A wavelet power-based index and the enhanced SWT scalogram were sequentially proposed to classify AE waves induced by different mechanisms according to their energy distributions in the time–frequency domain. A novel crack sizing method taking advantage of crack closure-induced AE waves was developed based on fatigue tests in the laboratory. The propagation characteristics of AE waves in the rail were investigated, and Tsallis synchrosqueezed wavelet entropy (TSWE) with time was finally brought forward to detect and locate rail cracks in the field. The proposed strategy for detection, location and sizing of rail cracks helps to ensure the safe and smooth operation of the railway system. This thesis is of interest to graduate students, researchers and practitioners in the area of structural health monitoring.

Available in PDF, EPUB and Kindle. Book excerpt: This book was proposed and organized as a means to present recent developments in the field of nondestructive testing of materials in civil engineering. For this reason, the articles highlighted in this editorial relate to different aspects of nondestructive testing of different materials in civil engineering—from building materials to building structures. The current trend in the development of nondestructive testing of materials in civil engineering is mainly concerned with the detection of flaws and defects in concrete elements and structures, and acoustic methods predominate in this field. As in medicine, the trend is towards designing test equipment that allows one to obtain a picture of the inside of the tested element and materials. From this point of view, interesting results with significance for building practices have been obtained

Available in PDF, EPUB and Kindle. Book excerpt: This book presents concepts, methods and techniques to examine symptoms of faults and failures of structures, systems and components and to monitor functional performance and structural integrity. The book is organized in five parts. Part A introduces the scope and application of technical diagnostics and gives a comprehensive overview of the physics of failure. Part B presents all relevant methods and techniques for diagnostics and monitoring: from stress, strain, vibration analysis, nondestructive evaluation, thermography and industrial radiology to computed tomography and subsurface microstructural analysis. Part C cores the principles and concepts of technical failure analysis, illustrates case studies, and outlines machinery diagnostics with an emphasis on tribological systems. Part D describes the application of structural health monitoring and performance control to plants and the technical infrastructure, including buildings, bridges, pipelines, electric power stations, offshore wind structures, and railway systems. And finally, Part E is an excursion on diagnostics in arts and culture. The book integrates knowledge of basic sciences and engineering disciplines with contributions from research institutions, academe, and industry, written by internationally known experts from various parts of the world, including Europe, Canada, India, Japan, and USA.

Available in PDF, EPUB and Kindle. Book excerpt: The Defense Metals Information Center conducted a brief survey of the present state of knowledge about fatigue with wide coverage to applications and with particular emphasis on means of early detection of fatigue damage. The survey has excluded consideration of reports of proprietary interest and of reports with security classification. However, it has included information from various branches of the U.S. Army, the U.S. Navy, the U.S. Air Force, and the National Aeronautics and Space Administration. The results of such considerations as have been possible are described in the following pages with the objectives of: (1) Delineating the current state of knowledge; (2) Indicating some of the current research toward increasing this knowledge; and (3) Pointing out areas where further work seems desirable.

Available in PDF, EPUB and Kindle. Book excerpt: The book presents theoretical and experimental studies to establish the relationship between volume jumps of the 90° domain wall in a ferromagnetic material and the magnitude of the half-space surface displacement caused by it. A method of evaluating the influence of the external magnetic field on the stress intensity factor at the tip of the crack-like defects in ferromagnets is discussed. The influence of hydrogen on the generation of magneto-elastic acoustic emission signals of ferromagnets is described. The features of magneto-elastic acoustic emission due to the presence of plastic deformation, structural changes, and volumetric damage in such structural materials are shown.
