Book Description
A Taylor Series correction to the maximum in plane shear stress was studied as a means of extending the data zone in photoelastic determination of stress intensity factors beyond the singular region of a two degree of freedom analysis. Convergence properties were obtained by comparing with several complete two-dimensional solutions. Experiments were performed on two kinds of three-dimensional problems; plates containing surface flaws in both bending and extension. Results were analyzed by both a two degree of freedom and a Taylor Series Correction Method (TSCM). (Author Modified Abstract).

Book Description
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.

Book Description
Thirty-five papers were presented at the International Symposium on Photoelasticity, Tokyo, 1986, representing fifty-five authors. Eighteen of these papers were presented by Japanese photoelasticians and seventeen by leading foreign authorities from eleven countries (Austria, Canada, Czechoslovakia, F.R. of Germany, France, Greece, India, Switzerland, UK, USA and USSR) • This is the first symposium on photoelasticity of international scope held in Japan. The primary objectives of this symposium are to help bridge the gap between photoelastic researchers around the world, to promote mutual understanding and communications and to facilitate exchange of newly acquired knowledge in theories and techniques. In addition, it is important that these valuable results are communicated effectively to engineers who can apply them in practice in industry. The papers presented at this symposium cover all branches of photo elasticity in a broad sense, including, in addition to long estab lished photoelasticity, newly developed moire, interferometric, and holographic photoelasticity, caustics and speckle. Therefore, from an optical stress analysis pe~spective, this volume is the latest compre hensive collection of photoelastic expertises.

Book Description
A technique is described for extracting stress intensity factors from photoelastic data which uses a Taylor Series expansion of the in-plane maximum shearing stress in conjunction with a digital computer program. By applying the method to a variety of problems including center cracked panels, compact tension specimens, part-circular surface flaws and flat bottomed surface flaws, characteristics of the method are demonstrated, and its strengths and weaknesses are delineated. It is concluded that stress freezing photoelasticity appears to be a potentially powerful tool for estimating stress intensity factors for complex three dimensional problems. (Author).

Book Description
This volume contains 132 selected papers presented at the Symposium which will be held on November 22-25, 1983 in Beijing and is the first of international symposia on fracture mechanics held in China. In this volume one may find the contributions of many internationally well known scientists and engineers is the field of fracture mechanics. Among the 132 papers from 12 countries and regions, 16 are invited lectures which were specially chosen to cover major trends in fracture mechanics and were prepared by specialists actively engaged on the respective subjects. All papers are grouped under the 6 headings, that is, 1. Elastic and elastic-plastic fracture mechanics; 2. Applications of fracture mechanics; 3. Test methods; 4. Fatigue; 5. Fracture models and micro-mechanisms and 6. Fracture of non-metals. 70 papers are from Chinese contributors. It is the first time that Chinese scientists and engineers working on this field presented their studies to the outside world in such a large number and wide range of topics. Anyone interested in fracture mechanics may find in this volume the recent advances in this field. Anyone interested in the development in China may find in this volume the state of the art of fracture mechanics studies in China. This proceedings may serve also as a reference book for engineers, applied mathematicians, metallurgists, physicists and other scientists, as well as graduate students and undergraduate students. There are approximately 1,100 pages.
