Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book A Survey of the Literature on the Size Effect on Material Strength written by H. Leon Harter and published by . This book was released on 1977 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly 500 years ago, Leonardo da Vinci observed that long wires are weaker than short wires of the same diameter. The statistical theory of extreme values (weakest-link theory) plays a very important role in studies of the size effect; competing theories include the energy theory and the technological theory. Summaries are given of relevant publications identified in the course of a literature survey on the size effect. Since this survey was motivated by concern about the reliability of large composite aircraft structures, which are now coming into use, special attention is given to the size effect on composite materials and structures. An attempt is made to summarize the present state of knowledge and to identify unsolved problems requiring further research.

Download or read book Three dimensional Stress Distribution Near a Sharp Crack in a Plate of Finite Thickness written by G. H. Sih and published by . This book was released on 1966 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: An attempt has been made to investigate the three-dimensional stress distribution near the tip of a semi-infinite crack embedded in an infinite plate of arbitrary thickness. The problem is formulated by means of three biharmonic functions in the classical theory of elasticity as developed by Galerkin. The eigenfunction expansion technique of Williams for solving two-dimensional crack problems is incorporated into the three-dimensional crack analysis. It is found that the stresses rr, theta theta, zz, r theta are singular of the order of r( -1/2), r being the distance measured from the crack point, but the transverse shear components rz, theta z are bounded everywhere in the plate. Determined in an approximate manner is the intensity of the crack-edge stress field which depends on the thickness coordinate of the plate. The results provide an improved understanding of the three-dimensional aspects of fracture theories, particularly on the effect of plate thickness.

Download or read book Recent Advances in Composite Materials written by E.E. Gdoutos and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains 31 papers presented at the symposium on "Recent Advances in Composite Materials" which was organized in honor of Professor Stephanos A. Paipetis. The symposium took place at Democritus University of Thrace, in Xanthi, Greece on June 12-14, 2003. The book is a tribute to Stephanos A. Paipetis, a pioneer of composite materials, in recognition of his continuous, original diversified and outstanding contributions for half a century. The book consists of invited papers written by leading experts in the field. It contains original contributions concerning the latest developments in composite materials. It covers a wide range of subjects including experimental characterization, analytical modeling and applications of composite materials. The papers are arranged in the following six sections: General concepts, stress and failure analysis, mechanical properties, metal matrix composites, structural analysis and applications of composite materials. The first section on general concepts contains seven papers dealing with composites through the pursuit of the consilience among them, computation and mechatronic automation of multiphysics research, a theory of anisotropic scattering, wave propagation, multi-material composite wedges, a three-dimensional finite element analysis around broken fibers and an in situ assessment of the micromechanics of large scale bridging in ceramic composites.

Download or read book Fracture and Size Effect in Concrete and Other Quasibrittle Materials written by Zdenek P. Bazant and published by CRC Press. This book was released on 1997-12-29 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fracture and Size Effect in Concrete and Other Quasibrittle Materials is the first in-depth text on the application of fracture mechanics to the analysis of failure in concrete structures. The book synthesizes a vast number of recent research results in the literature to provide a comprehensive treatment of the topic that does not give merely the facts - it provides true understanding. The many recent results on quasibrittle fracture and size effect, which were scattered throughout many periodicals, are compiled here in a single volume. This book presents a well-rounded discussion of the theory of size effect and scaling of failure loads in structures. The size effect, which is the most important practical manifestation of fracture behavior, has become a hot topic. It has gained prominence in current research on concrete and quasibrittle materials. The treatment of every subject in Fracture and Size Effect in Concrete and Other Quasibrittle Materials proceeds from simple to complex, from specialized to general, and is as concise as possible using the simplest level of mathematics necessary to treat the subject clearly and accurately. Whether you are an engineering student or a practicing engineer, this book provides you with a clear presentation, including full derivations and examples, from which you can gain real understanding of fracture and size effect in concrete and other quasibrittle materials.
