Constraint Effects in Fracture


Book Description

Papers presented at the symposium on [title] held in Indianapolis, Indiana, May 1991, provide a framework for quantifying constraint effects in terms of both continuum mechanics and micro-mechanical modeling approaches. Such a framework is useful in establishing accurate predictions of the fracture




IUTAM Symposium on Nonlinear Analysis of Fracture


Book Description

This volume constitutes the Proceedings of the IUTAM Symposium on 'Nonlinear Analysis of Fracture', held in Cambridge from 3rd to 7th Septem ber 1995. Its objective was to assess and place on record the current state of understanding of this important class of phenomena, from the standpoints of mathematics, materials science, physics and engineering. All fracture phenomena are nonlinear; the reason for inclusion of this qualification in the title was to reflect the intention that emphasis should be placed on distinctive aspects of nonlinearity, not only with regard to material consti tutive behaviour but also with regard to insights gained, particularly from the mathematics and physics communities, during the recent dramatic ad vances in understanding of nonlinear systems in general. The expertise represented in the Symposium was accordingly very wide, and many of the world's greatest authorities in their respective fields participated. The Symposium remained focussed on issues of practical significance for fracture phenomena, with concentration on aspects that are still im perfectly understood. The most significant unifying issue in this regard is that of scale: this theme was addressed from several perspectives. One important aspect is the problem of passing information on one scale up or down, as an input for analysis at another scale. Although this is not always the case, it may be that the microscopic process of fracture is understood in some particular class of materials.




Cracks and Fracture


Book Description

Cracks and Fracture consists of nine chapters in logical sequence. In two introductory chapters, physical processes in the vicinity of the crack edge are discussed and the fracture process is described. Chapter 3 develops general basic concepts and relations in crack mechanics, such as path independent integrals, stress intensity factors and energy flux into the crack edge region. Chapters 4-7 deal with elastostatic cracks, stationary or slowly moving elastic-plastic cracks, elastodynamic crack mechanics and elastoplastic aspects of fracture, including dynamic fracture mechanics. Appendices include general formulae, the basic theory of analytic functions, introduction to Laplace and Hankel transforms and description of certain basic relations, for instance for stress waves in solids. There is an extensive bibliography, containing references to both classical and recent work, and a comprehensive index.

Advances in Mechanical Behaviour, Plasticity and Damage


Book Description

Since its inception in 1991, EUROMAT has been held each year on behalf of the Federation of European Materials Societies (FEMS), and alternates between general and topical prospectives. This year's theme, Advances in Mechanical Behaviour, Plasticity and Damage, was proposed by the Societe Francaise de Metallurgie et de Materiaux (SF2M) to FEMS.This publication contains a selection of papers presented at the EUROMAT 2000 Conference, held in Tours, France on 7-9 November 2000. The aim of this Conference was to concentrate mainly on recent advances made in the investigation of the relationship between microstructures of materials and their mechanical behaviour; including, fundamentals, modelling and applications. Encompassed in the Conference's aim is the nurturing of the synergistic effect between the theoretical and applied areas in this field. This was achieved by addressing important basic and practical aspects of the mechanical behaviour and damage of materials whilst also providing significant links between various complementary approaches. All kinds of materials are covered and topics that were covered include the mechanics of solid polymers, microstructurs and micromechanisms, and the collective behavior of defects which looks at the interaction of multiple defects in a system.

Statistical Field Theories


Book Description

Recent developments in theoretical physics include new instances of the unification of quite different phenomena. The theoretical community is challenged by the growing interactions between high-energy physics, statistical physics, and condensed matter physics. The common language, though, is exact solutions of two-dimensional and conformable field theories. This volume is a faithful representation of this interdisciplinary domain. Conformable and integrable field theories have been active research topics for several decades. The main recent developments concern the boundary effects and applications to disordered systems. The number of applications of the exact methods to condensed-matter problems has been growing over the years. Nowadays it is widely recognized that strongly interacting systems in low dimensions can be successfully described by integrable and conformable theories. This volume is an indispensable aid to those seeking to find their way in this domain.

Shallow Crack Fracture Mechanics Toughness Tests and Applications


Book Description

Within the last decade there has been an increasing awareness that use of standards deeply notched fracture mechanics test specimens can result in substantial over-or-under-assessments of the real fracture toughness associated with shallow surface cracks.
