Determination of Stress State in Continuously Welded Rails -- Rev available in PDF, EPUB and Kindle. Summarizes findings and conclusions of an investigation of the state of stress in continuously welded rail using two techniques. The first involved acoustic analysis of rail vibration induced by an external excitation, based on the hypothesis that in-situ thermal stress in rail could be obtained from a calibration of its vibrational characteristics against stress. Tests were conducted on whole rail sections on a simulated half-track bed, with excitation of the rail head in vertical and lateral directions and of the web and foot of the rail using a ten-pound hammer. Rail response was measured by an accelerometer positioned opposite the impact point. The second technique involved magneto-elastic calibration of the magnetism of rail steel against applied stress, based on the principle of magneto-elastic interaction between magnetostrictive and elastic lattice strains. This phenomenon produces an electrical pulse called Barkhausen noise. Calibrations of Barkhausen noise levels versus stress were performed on rail samples from five different manufacturers. Field measurements on sections of Quebec Cartier Mining track are also analyzed and presented.

Download and read online ebook Structural and Residual Stress Analysis by Nondestructive Methods write by V. Hauk. This book was released on 1997-11-10. Structural and Residual Stress Analysis by Nondestructive Methods available in PDF, EPUB and Kindle. The field of stress analysis has gained its momentum from the widespread applications in industry and technology and has now become an important part of materials science. Various destructive as well as nondestructive methods have been developed for the determination of stresses. This timely book provides a comprehensive review of the nondestructive techniques for strain evaluation written by experts in their respective fields. The main part of the book deals with X-ray stress analysis (XSA), focussing on measurement and evaluation methods which can help to solve the problems of today, the numerous applications of metallic, polymeric and ceramic materials as well as of thin-film-substrate composites and of advanced microcomponents. Furthermore it contains data, results, hints and recommendations that are valuable to laboratories for the certification and accreditation of their stress analysis. Stress analysis is an active field in which many questions remain unsettled. Accordingly, unsolved problems and conflicting results are discussed as well. The assessment of the experimentally determined residual and structural stress states on the static and dynamic behavior of materials and components is handled in a separate chapter. Students and engineers of materials science and scientists working in laboratories and industries will find this book invaluable.
