Available in PDF, EPUB and Kindle. Book excerpt: An ultrasonic technique for determining the axial stress within a bolt was developed and experimentally verified. The technique uses time-of-flight measurements of both shear and longitudinal waves propagating along the axis of a bolt along with the material parameters to calculate the stress acting on the bolt. One significant advantage of the technique is that an independent measurement of neither the original nor present length is required. Experimental results suggest that the method may be usable for fasteners which have experienced a small amount of plastic deformation.

Download or read book An Ultrasonic Technique for the Measurement of Residual Stress written by PJ. Noronha and published by . This book was released on 1975 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ultrasonic shear wave technique to measure stress in metals is described. The technique utilizes a pulse-echo system operating at 7 MHz to measure changes in the time of travel of the ultrasonic shear wave to 1 part per million. Linear changes in the velocity of a shear wave occur with stress and are dependent on the higher order elastic constants of the material. The linear change in velocity with stress allows the definition of a constant called the stress acoustic constant for the material. The amount of birefringence in a specimen is measured, and after accounting for the portion caused by anisotropy of the material, the remainder gives an accurate measure of the residual stress in the material. The amount of birefringence caused by anisotropy is a constant for specimens having the same nominal mechanical and thermal treatments. Measurements using the ultrasonic technique of simulated residual stress, introduced by bending of a 6-ft (1.8-m) section of A-36 steel I-beam, yielded values in the vicinity of those measured using strain gage and O-ring techniques. Application of this technique to the measurement of other simple states of stress is suggested, along with the precautions to be observed for measuring stress.

Download or read book Structural and Residual Stress Analysis by Nondestructive Methods written by V. Hauk and published by Elsevier. This book was released on 1997-11-10 with total page 655 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Ultrasonic Measurement of Axial Stress written by JS. Heyman and published by . This book was released on 1982 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several applications of ultrasonic techniques are gaining acceptance for accurate preload determination of critical fasteners. In this presentation, one class of techniques based on continuous wave ultrasonics is examined in detail, with benefits and limitations discussed as they apply to accurate determination of fastener preload. The theory of acoustic propagation in strained media is reviewed as it applies to bolt geometries. Propagation measurements in these geometrics require an understanding of guided-wave effects which can influence stress determination. However, studies of the acoustic spectra of rods identify diffraction and resulting mode conversion as the main artifact for such a measurement. The acoustic spectra, obtained with a novel tone burst spectroscopy method, clearly show mode conversion effects at low frequencies to be absent at high frequencies.
