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.

This book was released on 1982 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrasonic measurements of the variation of elastic modulus with stress have been done for more than 30 years. The inverse problem of measuring residual stress by ultrasonic means is still poorly understood. As a result, the measurement of residual stress by ultrasonic means has not been a successful engineering method. A symposium describing the present state of the art has been held and the written record of some of the contributors to it is presented by the following set of papers.

Available in PDF, EPUB and Kindle. Book excerpt: Focusing on the theory and state-of-the-art technologies of ultrasonic testing (UT), this book examines ultrasonic propagation in solids and its detection applications, and explores the intersection of UT technology with various fields of electromagnetics, optics and physics. UT is one of the most widely used nondestructive testing techniques due to its high performance in terms of detection efficiency and safety. The rapid development of modern industrial products and technologies has created a new challenge and demand for ultrasonic nondestructive testing technology. This book introduces the fundamentals of UT, including sound wave and sound field, interface wave theory and liquid-solid coupled sound field. It then discusses various types of UT methods, ranging from the critically refracted longitudinal wave method to ultrasonic surface wave and ultrasonic guided wave detection methods. Some newly developed UT techniques are also discussed, including phased-array UT, high-frequency UT and non-contact UT. This title will appeal to engineering students and technicians in the field of ultrasonic nondestructive testing.

Available in PDF, EPUB and Kindle. Book excerpt: Shear wave birefringence in metal specimens has been studied as a possible method of nondestructively measuring residual stresses. It was established that the stress-induced birefringence in Al and steel varies linearly with the magnitude of an applied stress and does not change appreciably as these metals are deformed plastically. Other sources of birefringence were studied also. Preferred orientation is a major source especially in rolled metal stock. A pulse echo technique for observing shear wave birefringence is described and the current limitations are discussed. (Author).

This book was released on 2012 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: A significant challenge in determining the safety margin for gusset plates is determining the level of stresses carried in the plate. Present technologies are unable to evaluate the dead, live and residual stresses maintained in gusset plates. The goal of the research presented in this thesis is to improve the safety of highway bridges by developing and testing an ultrasonic stress measurement methodology for determining actual stress in steel gusset plates, evaluating the accuracy and precision of the measurements, and assess if the methodology has sufficient accuracy and precision to be a useful tool in the safety analysis of gusset plates. This research utilizes the acoustoelastic effect to evaluate actual stress levels by assessing the acoustic birefringence in a steel material. The birefringence measurement evaluates normalized variations of polarized shear waves propagating through the plate thickness, which vary proportionally as a function of stress. This thesis discusses exploratory testing to evaluate the potential of the approach as a tool for the condition assessment of gusset plates.
