Book Synopsis Experiments to Test a Systems Analysis of Brittle Fracture by : G. T. Hahn

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this program has been to simplify the complex problem of fracture of metals by a systems approach: for a given type or mode of failure, the basic simple parameters and mechanisms controlling failure are identified, these are treated individually by experiment and analysis, and the individual results are combined into a description of the failure process yielding predictions which can be checked by experiment. Except for the last portion of the program, the experiments were conducted on center cracked steel foils. In the earlier stages of work the analysis concentrated on predictions of the development of plasticity with loading and the conditions at which crack propagation begins. The work was then directed toward the problem of rapid crack propagation basing the analysis on previous results. The work has yielded a detailed description of crack propagation under plane stress conditions both in the form of an analytic model and experimental observations of crack speeds. A method for quantitatively measuring the energy absorption rate of a material during crack propagation has been tested. This method holds promise as a way of characterizing the intrinsic resistance to unstable crack propagation. Some of the concepts and methods developed have been applied to the very complex problem of calculating crack speeds in pipelines. (Author).
Book Synopsis The Fracture of Brittle Materials by : Stephen W. Freiman
Download or read book The Fracture of Brittle Materials written by Stephen W. Freiman and published by John Wiley & Sons. This book was released on 2012-02-03 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supports the use and development of strong, fracture-resistant, and mechanically reliable ceramic materials The Fracture of Brittle Materials thoroughly sets forth the key scientific and engineering concepts underlying the selection of test procedures for fracture toughness, strength determination, and reliability predictions. With this book as their guide, readers can confidently test and analyze a broad range of brittle materials in order to make the best use of existing materials as well as to support the development of new materials. The authors explain the importance of microstructure in these determinations and describe the use of quantitative fractography in failure analysis. The Fracture of Brittle Materials is relevant to a broad range of ceramic materials (i.e., any inorganic non-metal), including semiconductors, cements and concrete, oxides, carbides, and nitrides. The book covers such topics as: Basic principles of fracture mechanics underlying brittle material tests and analysis procedures Theory and mechanisms of environmentally enhanced crack growth Fracture mechanics tests to determine a material's resistance to fast fracture Test and analysis methods to assess the strength of ceramics Methods to analyze the fracture process based on quantitative measurements of the fracture surface Effect of a material's microstructure Methods for predicting the lifetime of brittle components under stress Throughout the book, figures and illustrations help readers understand key concepts and methods. Replete with real-world examples, this text enables engineers and materials and ceramics scientists to select and implement the optimal testing methods for their particular research needs and then accurately analyze the results.

Book Synopsis Advanced Methods of Fatigue Assessment by : Dieter Radaj
Download or read book Advanced Methods of Fatigue Assessment written by Dieter Radaj and published by Springer Science & Business Media. This book was released on 2013-05-13 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: In five chapters, this volume presents recent developments in fatigue assessment. In the first chapter, a generalized Neuber concept of fictitious notch rounding is presented where the microstructural support factors depend on the notch opening angle besides the loading mode. The second chapter specifies the notch stress factor including the strain energy density and J-integral concept while the SED approach is applied to common fillet welded joints and to thin-sheet lap welded joints in the third chapter. The forth chapter analyses elastic-plastic deformations in the near crack tip zone and discusses driving force parameters. The last chapter discusses thermomechanical fatigue, stress, and strain ranges.

Book Synopsis Brittle Fracture and Damage of Brittle Materials and Composites by : Jacques Lamon
Download or read book Brittle Fracture and Damage of Brittle Materials and Composites written by Jacques Lamon and published by Elsevier. This book was released on 2016-03-16 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flaws are the principal source of fracture in many materials, whether brittle or ductile, whether nearly homogeneous or composite. They are introduced during either fabrication or surface preparation or during exposure to aggressive environments (e. g. oxidation, shocks). The critical flaws act as stress concentrators and initiate cracks that propagate instantaneously to failure in the absence of crack arrest phenomena as encountered in brittle materials. This book explores those brittle materials susceptible to crack arrest and the flaws which initiate crack induced damage. A detailed description of microstructural features covering numerous brittle materials, including ceramics, glass, concrete, metals, polymers and ceramic fibers to help you develop your knowledge of material fracture. Brittle Failure and Damage of Brittle Materials and Composites outlines the technological progress in this field and the need for reliable systems with high performances to help you advance the development of new structural materials, creating advantages of low density, high resistance to elevated temperatures and aggressive environments, and good mechanical properties. The effects of flaw populations on fracture strength The main statistical-probabilistic approaches to brittle fracture The use of these methods for predictions of failure and effects induced by flaw populations The application of these methods to component design The methods of estimation of statistical parameters that define flaw strength distributions The extension of these approaches to damage and failure of continuous fiber reinforced ceramic matrix composites

Book Synopsis Design, Development, and Characterization of an Experimental Device to Test Torsion-controlled Fracture of Thin Brittle Rods by : Ronald Henry Heisser
Download or read book Design, Development, and Characterization of an Experimental Device to Test Torsion-controlled Fracture of Thin Brittle Rods written by Ronald Henry Heisser and published by . This book was released on 2016 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: As research continues to uncover the many different physical properties of meso- and microscale materials, it becomes more evident that these materials often behave in counterintuitive ways. Characterizing unique phenomena not only provides analogies in nature which inspire innovation at all levels of research and design but also presents new possibilities for future technological development. The discussion presented herein explores the design and development of a low-cost, manual device intended to test a hypothesis rooted in the behavior of breaking pasta that intrigued even Richard Feynman. While the mechanism for why spaghetti breaks into three or more pieces has been described, the experimental discussion presented here focuses on the effect that added torsion has on the fracture bent spaghetti. Specifically, it is possible that twisting the spaghetti a critical angle and bending it will cause it to fracture into only one piece. The idea of torsion being used to exhibit some control over how a material fractures has not been well-investigated; the results which come from this experiment may prove useful for applications even beyond the scope of thin brittle materials. With this said, the sensitivity in quantifying breaking from torsion and bending together requires that the experimental device prevent systematic error stress from negatively impacting the accuracy of the experiment. Thus much time is devoted to explanation and rationale behind the analysis of the experimental device. Alongside the device's characterization this thesis serves to be a reflection of the design process taken while creating this device. Lessons learned from this project are included in all aspects of the discussion and a section in the Appendix is devoted to a more detailed account of the design and fabrication of one device component.
