Download or read book Some Basic Problems of the Mathematical Theory of Elasticity written by N.I. Muskhelishvili and published by Springer Science & Business Media. This book was released on 1977-04-30 with total page 774 pages. Available in PDF, EPUB and Kindle. Book excerpt: TO THE FIRST ENGLISH EDITION. In preparing this translation, I have taken the liberty of including footnotes in the main text or inserting them in small type at the appropriate places. I have also corrected minor misprints without special mention .. The Chapters and Sections of the original text have been called Parts and Chapters respectively, where the latter have been numbered consecutively. The subject index was not contained in the Russian original and the authors' index represents an extension of the original list of references. In this way the reader should be able to find quickly the pages on which anyone reference is discussed. The transliteration problem has been overcome by printing the names of Russian authors and journals also in Russian type. While preparing this translation in the first place for my own informa tion, the knowledge that it would also become accessible to a large circle of readers has made the effort doubly worthwhile. I feel sure that the reader will share with me in my admiration for the simplicity and lucidity of presentation.

Download or read book Fracture Scaling written by Zdenek P. Bazant and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a collection of the papers given at the workshop on Fracture Scaling, held at the University of Maryland, USA, 10-12 June 1999, under the sponsorship of the Office of Naval Research, Arlington, VA, USA. These papers can be grouped under five major themes: Micromechanical analysis Size effects in fiber composites Scaling and heterogeneity Computational aspects and nonlocal or gradient models Size effects in concrete, ice and soils . This workshop is the result of a significant research effort, supported by the Office of Naval Research, into the problems of scaling of fracture in fiber composites, and generally into the problems of scaling in solid mechanics. These problems, which are of interest for many materials, especially all quasibrittle materials, share similar characteristics. Thus, progress in the understanding of scaling problems for one material may help progress for another material. This makes it clear that a dialogue between researchers in various fields of mechanics is highly desirable and should be promoted. In view of this, this volume should be of interest to researchers and advanced graduate students in materials science, solid mechanics and civil engineering.
Download or read book Residual Stress Analysis on Welded Joints by Means of Numerical Simulation and Experiments written by Paolo Ferro and published by BoD – Books on Demand. This book was released on 2018-05-16 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to quantify residual stresses induced by welding processes through experimentation or numerical simulation has become, today more than ever, of strategic importance in the context of their application to advanced design. This is an ongoing challenge that commenced many years ago. Recent design criteria endeavour to quantify the effect of residual stresses on fatigue strength of welded joints to allow a more efficient use of materials and a greater reliability of welded structures. The aim of the present book is contributing to these aspects of design through a collection of case-studies that illustrate both standard and advanced experimental and numerical methodologies used to assess the residual stress field in welded joints. The work is intended to be of assistance to designers, industrial engineers and academics who want to deepen their knowledge of this challenging topic.

Download or read book Fracture and Complexity written by Alberto Carpinteri and published by Springer Nature. This book was released on 2021-06-26 with total page 968 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book explores the two opposite natural trends of composite systems: (i) order and structure emerging from heterogeneity and randomness, and (ii) instability and chaos arising from simple nonlinear rules. Providing insights into the rapidly growing field of complexity sciences, the book focuses on the role of complexity in fracture mechanics. It firstly discusses the occurrence of self-similarity and fractal patterns in deformation, damage, fracture, and fragmentation of heterogeneous materials and the apparent scaling of the nominal mechanical properties of disordered materials, as well as of the time-to-failure after fatigue and creep loading. Then the book addresses criticality in the acoustic emissions from damaged structures and tectonic faults. Further, it examines the snap-back instability in the structural behavior of relatively large composite structures in the framework of catastrophe theory, and lastly describes the transition toward chaos in the dynamics of cracked elements.

Download or read book On the Singular Stress Field at the Interface of Bimaterial Systems written by Mingan Tan and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inverse square root, 1/r, singularity characterizes the stress field at the crack tip of homogeneous isotropic elastic media. This 1/r singularity does not, however, hold for the stress field at the interface of a bimaterial system. A number of attempts have been made to treat this class of problems. These attempts reveal the presence of rapid oscillations in the stress and displacement fields and the dependence of the stress singularities upon the geometry and the elastic mismatch of the bimaterial system. These features complicate the determination of the singular stress field significantly. As a result, existing solutions are limited to a few specific configurations and simple loading conditions. It is, therefore, the objective of this thesis to develop a unified approach for treating general bimaterial systems. For this purpose, the bimaterial system is modeled as a bimaterial wedge, thus facilitating the simulation of a wide range of inhomogeneous solids--such as, layered composite materials, coated components and welded structures. Both theoretical and experimental techniques are employed to examine the current problem and the resulting singular stress field. The current boundary value problem is formulated in terms of the complex function method. By examining the resultant eigenequation of the system, the dependence of the stress singularities upon wedge geometry and elastic properties of the constituents is revealed and explicit expressions for the stress and displacement fields around the wedge vertex are obtained. These expressions are then used to develop a new singular finite element. This element enables the determination of the singular stress field and the associated stress intensity factors reliably and efficiently. Both quasi-static and dynamic stress intensity factors are obtained explicitly. To establish the validity of the newly developed method, a number of test cases are examined and compared with existing simplified solutions. The newly proposed method is then used to evaluate the effect of the wedge geometry, elastic mismatch, density ratio and loading conditions upon the resulting stress intensity factors. In the experimental work, a digital photoelastic technique is employed to examine the singular stress field around the vertex of a photoelastic bimaterial wedge. A special casting procedure is introduced to produce bimaterial photoelastic specimens with varied geometries. To determine the stress intensity factors reliably from the resulting isochromatic fringe patterns, a high order representation of the stress field around the vertex is used and a multi-parameter analysis method is developed. The experimental results are compared with the theoretical findings and the results reveal a good agreement between them.
Download or read book Security and Reliability of Damaged Structures and Defective Materials written by Guy Pluvinage and published by Springer Science & Business Media. This book was released on 2009-07-06 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structures that are essential for economy and security such as energy production, transportation and supply, water supply, buildings, are susceptible to failure, because of defects already present in the material, or created at fabrication, or appearing during service. Methods of assesment of the nocivity of these defects are needed, to predict the remaining service life and the eventual emergency of stopping service and repairing, if possible. To reach this objectives, this book presents the last methods derived from the classical linear, non-linear fracture mechanics concepts, including fatigue and notch fracture mechanics. Several examples of structures rehabilitations and repairing are given. This book gathers the presentation made during the Advanced Research Workshop held in Portoroz (Slovenia) in October 2008, under the auspices of NATO Science for Peace and Security Programme. It is edited by Professor Guy Pluvinage from the University Paul Verlaine – Metz (France) and Professor Aleksandar Sedmak from the University of Belgrade, Faculty of Mechanical Engineering. Both have a long and rich experience in analysis of theoretical and practical cases in safety and reliability of structures. Other contributors are all known as experts in the areas of fatigue, facture and reliability of structures.
