Available in PDF, EPUB and Kindle. Book excerpt: When asked to start teaching a course on engineering fracture mechanics, I realized that a concise textbook, giving a general oversight of the field, did not exist. The explanation is undoubtedly that the subject is still in a stage of early development, and that the methodologies have still a very limited applicability. It is not possible to give rules for general application of fracture mechanics concepts. Yet our comprehension of cracking and fracture beha viour of materials and structures is steadily increasing. Further developments may be expected in the not too distant future, enabling useful prediction of fracture safety and fracture characteristics on the basis of advanced fracture mechanics procedures. The user of such advanced procedures m\lst have a general understanding of the elementary concepts, which are provided by this volume. Emphasis was placed on the practical application of fracture mechanics, but it was aimed to treat the subject in a way that may interest both metallurgists and engineers. For the latter, some general knowledge of fracture mechanisms and fracture criteria is indispensable for an apprecia tion of the limita tions of fracture mechanics. Therefore a general discussion is provided on fracture mechanisms, fracture criteria, and other metal lurgical aspects, without going into much detail. Numerous references are provided to enable a more detailed study of these subjects which are still in a stage of speculative treatment.
Download or read book A Study of Plastic Deformation and Fracturing by Strain Energy Distribution Internally notched Steel Plates Under Tension written by S. I. Liu and published by . This book was released on 1950 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: This investigation was conducted to study the plastic deformation and fracturing of 12in. wide, 3/4in. thick internally notched steel plates under axial tension by determining the strain energy distribution on the surface of the deformed regions of the plates. Several stages in the process of deformation and fracturing at 70F and 10F were investigated to maximum load, 70F being above the transition temperature, and 10F being below the transition temperature. Surface strain energy distribution across the crack was also determined for a specimen fractured ductilely at 70F. The results of this investigation show that the total energy based on octahedral theory and the above-stated assumptions agrees very well with the total observed energy input; that the rate of propagation of plastic deformation with respect to energy input decreases with decreasing temperature; that, for specimens with two dimensional similarity and constant thickness, the total energy of individual specimens of varying width can be predicted by the strain energy distribution of a single specimen of proper width; and that, at room temperature, the unit strain energy at the crack is found to be approximately in the order of 30,000 in-lbs per cubic inch in a ductile specimen.

Download or read book Fracture Mechanics Criteria and Applications written by E.E. Gdoutos and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is difficult to do justice to fracture mechanics in a textbook, for the subject encompasses so many disciplines. A general survey of the field would serve no purpose other than give a collection of references. The present book by Professor E. E. Gdoutos is refreshing because it does not fall into the esoteric tradition of outlining equations and results. Basic ideas and underlying principles are clearly explained as to how they are used in application. The presentations are concise and each topic can be understood by advanced undergraduates in material science and continuum mechanics. The book is highly recommended not only as a text in fracture mechanics but also as a reference to those interested in the general aspects of failure analysis. In addition to providing an in-depth review of the analytical methods for evaluating the fundamental quantities used in linear elastic fracture mechanics, various criteria are discussed re:O. ecting their limitations and applications. Par ticular emphases are given to predicting crack initiation, subcritical growth and the onset of rapid fracture from a single criterion. Those models in which it is assumed that the crack extends from tip to tip rely on the specific surface energy concept. The differences in the global and energy states before and after crack extension were associated with the energy required to create a unit area of crack surface. Applications were limited by the requirement of self-similar crack growth.

Download or read book Mechanical Effects of Welding written by Lennart Karlsson and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Union of Theoretical and Applied Mechanics (IUTAM) initiated and sponsored an International Symposium on The Mechanical Effects of Welding. was held in Lulea, Sweden, 10-14 June 1991. The intention of the The Symposium Symposium was to gather active scientists in order to assess the current state of the art and future directions. The field of welding is an area which includes a large number of scientific disciplines, such as materials science, solid mechanics, thermal science, and also mechanical engineering design and production engineering. The intention of the Symposium was to cover the direct mechanical effects of welding and their influence on the in-service behaviour of welded structures. The Mechanical Effects of Welding is a very appropriate theme for an IUTAM Symposium. Progress in this field requires close interaction between researchers in several disciplines. This is reflected in the topics covered. The topics of the different sessions were: o Calculations of Temperatures, Strains and Stresses o Residual Stresses and Residual Deformations o Measurements of Residual Strains and Stresses o Effects of Defects and Residual Stresses on Fracture and Fatigue o Effects of Residual Stresses on Creep Deformation o Effects of Residual Deformations and Residual Stresses on Buckling There were 50 participants from 12 countries at the Symposium. The 28 papers presented at the Symposium are collected in this volume. A Scientific Committee, appointed by the Bureau of IUTAM, selected the participants to be invited and the papers to be presented.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Research on the Strength and Fracture of Materials: Volume 3Bs—Applications and Non-Metals contains the proceedings of the Fourth International Conference on Fracture, held at the University of Waterloo, Canada, in June 1977. The papers review the state of the art with respect to testing of fracture in a wide range of non-metals such as ceramics, glass, composites, polymers, biomaterials, and concrete. This volume is divided into five sections and opens by discussing the role of acoustic emission in fracture toughness testing and the relation between static and dynamic fracture toughness of structural steels. The reader is then introduced to methods for determining stress-intensity factors of simplified geometries of structural parts; stress analysis of pressure vessels by thermal shock; the fracture toughness of constructional steels in cyclic loading; and fracture processes and fracture toughness in powder forged steels. The remaining chapters explore the influence of low-cycle damage on fracture toughness; fracture of structural alloys at temperatures approaching absolute zero; fracture mechanisms in Si-Al-O-N ceramics; propagation and bifurcation of cracks in quartz; and the effect of pressure and environment on the fracture and yield of polymers. This monograph will be a useful resource for metallurgists, materials scientists, and structural and mechanical engineers.
