Book Description
The bending of a plate containing a centrally located, through crack is analyzed. Results are obtained numerically via a finite element analysis based on the assumptions of Mindlin sixth order plate theory, which admits three boundary conditions at any point and includes the effects of transverse shear. Elastic and elasto-plastic results are presented for two cases, one that includes the effects of closure and one that does not. The influence of closure on the local displacements, stress distributions, bending stress intensity factors, crack tip blunting, and the growth of the plastic enclave is demonstrated. The effect of thickness and the significance of transverse shear is also discussed. The results show that boundary conditions are critical to the modelling process, that the effects of closure are significant and must be included when demanded by the actual physical situation, and that the important issues regarding the plate bending problem have been identified and analyzed, so that issues regarding more detailed behavior may be addressed.

Book Description
The stress and strain in an elasto-plastic plate containing a crack have been obtained. The large deformations and general work-hardening have been taken into consideration. In addition, the results are used to predict a fracture stress as a function of the material's mechanical properties.

Fracture Mechanics Criteria and Applications
Author: E.E. GdoutosPublisher: Springer Science & Business Media
ISBN: 9400919565
Category : Science
Languages : en
Pages : 326
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
Recent advances in the field of fracture of engineering materials and structures have increasingly indicated its multidisciplinary nature. This area of research now involves scientists and engineers who work in materials science, applied mathematics and mechanics, and also computer scientists. The present volume, which contains the Proceedings of the Joint FEFG/lCF International Conference on Fracture of Engineering Materials and Structures held in Singapore from the 6th to 8th of August 1991, is a testimony of this multidisciplinary nature. This International Conference was the Second Symposium of the Far East Fracture Group (FEFG) and thus provided a unique opportunity for researchers and engineers in the Far East region to exchange and acquire knowledge of new advances and applications in fracture. The Conference was also the Inter-Quadrennial International Conference on Fracture (ICF) for 1991 and thus appealed to researchers in the international arena who wished to take advantage of this meeting to present their findings. The Conference has brought together over 130 participants from more than 24 countries, and they represented government and industrial research laboratories as well as academic institutions. It has thus achieved its objective of bringing together scientists and engineers with different backgrounds and perspectives but with . a common interest in new developments in the fracture of engineering materials and structures. This volume contains 4 keynote papers, 4 invited papers and 130 contributed papers.
