Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive overview of the whole field of fatigue and fracture of metallic materials covers both the theoretical background and some of the latest experimental techniques. It provides a summary of the complex interactions between material microstructure and cracks, classifying them with respect to the overall damage process with a focus on microstructurally short cracks and dynamic embrittlement. It furthermore introduces new concepts for the numerical treatment of fatigue microcrack propagation and their implementation in fatigue-life prediction models.This comprehensive overview of the whole field of fatigue and fracture of metallic materials covers both the theoretical background and the latest experimental techniques.

This book was released on 2012-12-06 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this jOint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 40 (thesis year 1995) a total of 10,746 thesis titles from 19 Canadian and 144 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 40 reports theses submitted in 1995, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Download or read book Environmentally Assisted Crack Growth in Structural Alloys written by Robert P. Wei and published by . This book was released on 1990 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmentally assisted crack growth (namely, stress corrosion cracking and corrosion fatigue) in structural alloys is one of the principal factors that determine the durability and reliability of engineering structures. Quantitative understanding of the micromechanics for cracking and of the processes that control crack growth, and modeling of crack growth response in terms of these micromechanisms and controlling processes are essential for the development of new and improved alloys and of more, reliable methods for life prediction. Research supported, in part, by the Office of Naval Research and Lehigh, over the past two and one-half decades has played a major role in transforming the activities in this area from that of screening and qualitative characterization of the phenomena to that of quantitative assessment and scientific understanding. Keywords: Environmental effects; Fracture mechanics; Crack growth; Corrosion fatigue; Stress corrosion cracking electrochemistry; Corrosion; Modeling; Steels. (JS).
Download or read book Multiscale Fatigue Crack Initiation and Propagation of Engineering Materials Structural Integrity and Microstructural Worthiness written by George C. Sih and published by Springer Science & Business Media. This book was released on 2008-06-01 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: What can be added to the fracture mechanics of metal fatigue that has not already been said since the 1900s? From the view point of the material and structure engineer, there are many aspects of failure by fatigue that are in need of attention, particularly when the size and time of the working components are changed by orders of magnitude from those considered by st traditional means. The 21 century marks an era of technology transition where structures are made larger and devices are made smaller, rendering the method of destructive testing unpractical. While health monitoring entered the field of science and engineering, the practitioners are discovering that the correlation between the signal and the location of interest depends on a priori knowledge of where failure may initiate. This information is not easy to find because the integrity of the physical system will change with time. Required is software that can self-adjust in time according to the monitored data. In this connection, effective application of health monitoring can use a predictive model of fatigue crack growth. Earlier fatigue crack growth models assumed functional dependence on the maximum stress and the size of the pre-existing crack or defect. Various possibilities were examined in the hope that the data could be grouped such that linear interpolation would apply.
Download or read book On Understanding Environment Enhanced Fatigue Crack Growth A Perspective View 1968 1977 written by R. P. Wei and published by . This book was released on 1978 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion fatigue (CF) is a generic term that is used to describe the phenomenon of cracking (including environment enhanced fatigue crack growth) in materials under the conjoint actions of an applied cyclic stress and a corrosive (aggressive) environment. It has been recognized as an important cause for failure of engineering structures. Characterization and understanding of corrosion fatigue are essential to service life prediction, fracture control, and the development of fatigue resistant alloys. Quantitative characterization and understanding have been hampered by the complexity of the problem, difficulties in separating the effects associated with crack initiation and with crack growth, and the absence of truly interdisciplinary attack of this problem.

This book was released on 1987 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmentally assisted crack growth (namely, stress corrosion cracking and corrosion fatigue) in alloys is one of the principal determining factors for durability and reliability of engineering structures. Over the past 20 years, activities in this area have transformed from principally that of screening and qualitative characterizations of the phenomena, to that of quantitative assessment and scientific understanding. This work has enabled the recent development of life prediction procedures. In this paper, the contributions of fracture mechanics in this transformation are reviewed. Current mechanistic understanding and environmentally assisted crack growth by hydrogen embrittlement is summarized, and is placed in perspective. Applications to mitigate stress corrosion and corrosion fatigue cracking in marine environments are summarized. Some outstanding issues and new directions for research are discussed. Keywords: Crack propagation, aluminum alloys; titanium alloys; steels; corrosion fatigue; fracture mechanics.
