Download or read book Application of Ultrasonic Fatigue Testing Techniques to the Evaluation of the Corrosion Fatigue Strength of Materials written by LD. Roth and published by . This book was released on 1984 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: A corrosion fatigue testing system has been developed for examining the corrosion-fatigue strength of engineering materials in the very high cycle regime (109 to 1010 cycles) typical of many design lifetimes. Central to this resonant fatigue testing system is a high efficiency, large displacement, piezoelectric transducer which operates at a frequency of 20 kHz, thus enabling the accumulation of large numbers of cycles in a reasonable amount of time. A description of apparatus, environmental controls, and testing method is presented. Experimental 20 kHz and low frequency corrosion fatigue results for a number of engineering materials, including a 12% chromium stainless steel, show similar reductions in fatigue limit at a specified number of cycles, despite the difference in frequency. This result holds for a variety of aqueous environments with and without electrochemical controls imposed during testing. The data illustrate the capabilities of the ultrasonic corrosion-fatigue technique and are analyzed to assess its advantages and limitations.
Download or read book Ultrasonics International 83 written by Sam Stuart and published by Elsevier. This book was released on 2013-09-11 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrasonics International 83 contains the proceedings of the Ultrasonics International Conference held in Halifax, Canada, on July 12-14, 1983. The papers focus on the role of ultrasound in various fields such as non-destructive testing, aerospace, high power, and medicine. The papers are organized into 24 sessions, which first discuss the applications of ultrasonics in aerospace. The session on non-destructive testing then describes ultrasonic applications including automatic in-motion inspection of the tread of railway wheels by EMA excited Rayleigh waves; effect of material deformation on the velocity of critically refracted shear waves in railroad rail; and crack depth estimation using wideband laser generated surface acoustic waves. The next session is concerned with medical ultrasonics and includes papers exploring the use of reflectivity tomography in attenuating media, wave propagation in biological tissue, and ultrasonic Doppler measurement of blood flow volume rate in the abdomen. The sessions that follow consider acoustic emission, visualization, material characterization, optoacoustics, and the physics of ultrasonics. High power and underwater ultrasonics, acoustic microscopy, transducers, and instrumentation are also discussed. This monograph will be of value to physicists and other scientists interested in ultrasonics.
Download or read book Ultrasonics written by Dale Ensminger and published by CRC Press. This book was released on 2024-02-21 with total page 904 pages. Available in PDF, EPUB and Kindle. Book excerpt: Updated, revised, and restructured to reflect the latest advances in science and applications, the fourth edition of this best-selling industry and research reference covers the fundamental physical acoustics of ultrasonics and transducers, with a focus on piezoelectric and magnetostrictive modalities. It then discusses the full breadth of ultrasonics applications involving low power (sensing) and high power (processing) for research, industrial, and medical use. This book includes new content covering computer modeling used for acoustic and elastic wave phenomena, including scattering, mode conversion, transmission through layered media, Rayleigh and Lamb waves and flexural plates, modern horn design tools, Langevin transducers, and material characterization. There is more attention on process monitoring and advanced nondestructive testing and evaluation (NDT/NDE), including phased array ultrasound (PAUT), long-range inspection, using guided ultrasonic waves (GUW), internally rotary inspection systems (IRIS), time-of-flight diffraction (TOFD), and acoustic emission (AE). These methods are discussed and applied to both metals and nonmetals using illustrations in various industries, including now additionally for food and beverage products. The topics of defect sizing, capabilities, and limitations, including the probability of detection (POD), are introduced. Three chapters provide a new treatment of high-power ultrasonics, for both fluids and solids, and again, with examples of industrial engineering, food and beverage, pharmaceuticals, petrochemicals, and other process applications. Expanded coverage is given to medical and biological applications, covering diagnostics, therapy, and, at the highest powers, surgery. Key Features Provides an overview of fundamental analysis and transducer technologies needed to design and develop both measurement and processing systems Considers applications in material characterization and metrology Covers ultrasonic nondestructive testing and evaluation and high-power ultrasonics, which involves interactions that change the state of material Highlights medical and biomedical applications of ultrasound, focusing on the physical acoustics and the technology employed for diagnosis, therapy, surgery, and research This book is intended for both the undergraduate and graduate scientists and engineers, as well as the working professional, who seeks to understand the fundamentals together with a holistic treatment of the field of ultrasonics and its diversity of applications.
Download or read book An Ultrasonic Technique for Detection of the Onset of Fatigue Damage written by Robert E Green (Jr) and published by . This book was released on 1972 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the research is to develop an ultrasonic techniques for the detection of the onset of fatigue damange. Particular emphasis is placed on the use of ultrasonic attenuation measurements as a continuous monitor of fatigue damage during cyclic testing of metal specimens. Efforts to date have indicated that the history of attenuation during fatigue of the specimen provide an index as to the onset of failure. Ultrasonic attenuation measurements made simultaneously with fatigue tests on aluminum bars give an early warning of eminent fracture. Such a warning occurs much earlier than detection of energy reflected from a crack by conventional ultrasonic techniques. This is true for specimens which were initially defect free and for those which initially had structural defects. A systematic comparison is being made between ultrasonic attenuation and other ultrasonic techniques, principally surface wave techniques and acoustic emission techniques. (Author).

This book was released on 2018-12-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the final reports of the scientific projects funded within the DFG-SPP1466 and, hence, provides the reader with the possibility to familiarize with the leading edge of VHCF research. It draws a balance on the existing knowledge and its enhancement by the joint research action of the priority program. Three different material classes are dealt with: structural metallic materials, long-fiber-reinforced polymers and materials used in micro-electro-mechanical systems. The project topics address the development of suitable experimental techniques for high-frequency testing and damage monitoring, the characterization of damage mechanisms and damage evolution, the development of mechanism-based models and the transfer of the obtained knowledge and understanding into engineering regulations and applications.
Download or read book Determination of Fatigue Limit Between 105 and 109 Cycles Using an Ultrasonic Fatigue Device written by C. Bathias and published by . This book was released on 1993 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-power ultrasound was used to study fatigue behavior of three alloys (Udimet 500, 17-4PH, and Ti-6A1-4V) since the loading frequency is very high (f = 20 kHz) and a great number of cycles can be obtained in a short time. The specimens were excited in resonance at the first longitudinal mode in such a way that maximum strain occurred in the middle and maximum displacement amplitude was obtained at the end of the specimen. Fatigue life behavior of the three alloys were investigated at ultrasonic (/ = 20 kHz) and conventional loading frequency (f = 20 to 50 Hz). Miniature dynamic strain gages were employed to measure maximum strain values during ultrasonic fatigue tests. The effect of high strain rate on fatigue crack initiation and propagation failure mechanism was examined. Fracture surface of specimens was observed by means of a scanning electron microscope. Fatigue resistance was found to depend upon ultrasonic and mechanical characteristics and microstructure of the material, loading regime, and surface condition of the specimen.
