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.

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).

This book was released on 2012-12-06 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue failure is a multi-stage process. It begins with the initiation of cracks, and with continued cyclic loading the cracks propagate, finally leading to the rupture of a component or specimen. The demarcation between the above stages is not well-defined. Depending upon the scale of interest, the variation may span three orders of magnitude. For example, to a material scientist an initiated crack may be of the order of a micron, whereas for an engineer it can be of the order of a millimetre. It is not surprising therefore to see that investigation of the fatigue process has followed different paths depending upon the scale of phenomenon under investigation. Interest in the study of fatigue failure increased with the advent of industrial ization. Because of the urgent need to design against fatigue failure, early investiga tors focused on prototype testing and proposed failure criteria similar to design formulae. Thus, a methodology developed whereby the fatigue theories were proposed based on experimental observations, albeit at times with limited scope. This type of phenomenological approach progressed rapidly during the past four decades as closed-loop testing machines became available.

This book was released on 2012-01-19 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many modern energy systems are reliant on the production, transportation, storage, and use of gaseous hydrogen. The safety, durability, performance and economic operation of these systems is challenged by operating-cycle dependent degradation by hydrogen of otherwise high performance materials. This important two-volume work provides a comprehensive and authoritative overview of the latest research into managing hydrogen embrittlement in energy technologies.Volume 2 is divided into three parts, part one looks at the mechanisms of hydrogen interactions with metals including chapters on the adsorption and trap-sensitive diffusion of hydrogen and its impact on deformation and fracture processes. Part two investigates modern methods of modelling hydrogen damage so as to predict material-cracking properties. The book ends with suggested future directions in science and engineering to manage the hydrogen embrittlement of high-performance metals in energy systems.With its distinguished editors and international team of expert contributors, Volume 2 of Gaseous hydrogen embrittlement of materials in energy technologies is an invaluable reference tool for engineers, designers, materials scientists, and solid mechanicians working with safety-critical components fabricated from high performance materials required to operate in severe environments based on hydrogen. Impacted technologies include aerospace, petrochemical refining, gas transmission, power generation and transportation. - Summarises the wealth of recent research on understanding and dealing with the safety, durability, performance and economic operation of using gaseous hydrogen at high pressure - Chapters review mechanisms of hydrogen embrittlement including absorption, diffusion and trapping of hydrogen in metals - Analyses ways of modelling hydrogen-induced damage and assessing service life
