Despite significant advances in technology and equipment for rolled steel, the computerization of production processes and the steady increase in production of sheet steel, recent scientific and technological achievements have not been compiled in the special literature and revealed to a wide range of specialists. This book details new approaches, computational techniques, and reliable calculation methods of leaf-rolling modes, forecasting and optimization of the technologies, increasing productivity of the mill and a radical improvement in the quality of steel products.
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 book explores the theoretical background of one of the most widespread activities in hydrocarbon wells, that of hydraulic fracturing. A comprehensive treatment of the basic phenomena includes: linear elasticity, stresses, fracture geometry and rheology. The diverse concepts of mechanics are integrated into a coherent description of hydraulic fracture propagation. The chapters in the book are cross-referenced throughout and the connections between the various phenomena are emphasized. The book offers readers a unique approach to the subject with the use of many numerical examples.
Despite tremendous advances made in fracture mechanics of concrete in recent years, very little information has been available on the nature of fracture processes and on reliable test methods for determining parameters for the different models. Moreover, most texts on this topic discuss numerical modeling but fail to consider experimentation. This book fills these gaps and synthesizes progress in the field in a simple, straightforward manner geared to practical applications.
Modern analytical theories of fatigue coupled with a knowledge of processing effects on metals make up the sound basis for designing machine parts that are free from unexpected failure. Fatigue Design: Life Expectancy of Machine Parts provides the information and the tools needed for optimal design. It highlights practical approaches for effectively solving fatigue problems, including minimizing the risk of hidden perils that may arise during production processes or from exposure to the environment. The material is presented with a dual approach: the excellent coverage of the theoretical aspects is accented by practical illustrations of the behavior of machine parts. The theoretical approach combines the fundamentals of solid mechanics, fatigue analysis, and crack propagation. The chapters covering fatigue theories are given special emphasis, starting with the basics and progressing to complicated multiaxial nonlinear problems. The practical approach concentrates on the effects of surface processing on fatigue life and it illustrates many faceted fatigue problems taken from case studies. The solutions demonstrate the authors' detailed analyses of failure and are intended to be used as preventive guidelines. The cases are a unique feature of the book. The numerical method used is the finite element method, and is presented with clear explanations and illustrations. Fatigue Design: Life Expectancy of Machine Parts is an extremely valuable tool for both practicing design engineers and engineering students.
The study of fracture mechanics of materials provides crucial information relating to the performance, integrity, durability and failure mode of individual components of a structure, and ultimately of an entire structure. Given the widespread and increasing use of cement and concrete materials in modern construction, it is essential that civil and structural engineers fully understand the mechanical properties of the materials they are specifying, and have a clear insight into their advantages and limitations. This book provides a comprehensive and readable exposition of this complex subject. This book should be of interest to structural, civil and mechanical engineers involved in design of new structures and testing and assessment of existing structures, as well as those concerned with researching materials properties, performance and design-life.
Restraint and intrinsic stresses in concrete at early ages are
vitally important for concrete structures which must remain free of
water-permeable cracks, such as water-retaining structures, tunnel
linings, locks and dams. The development of hydration heat,
stiffness and strength, also the degree of restraint and,
especially for high-strength concrete, non-thermal effects, are
decisive for sensitivity to cracking. Determining thses stresses in
the laboratory and in construction components has led to a clearer
understanding of how they develop and how to optimize mix design,
temperature and curing conditions. New testing equipment has
enabled the effects of all the important parameters to be qualified
and more reliable models for predictiong restraint stresses to be
developed.
Flexural-Torsional Buckling of Structures provides an up-to-date, comprehensive treatment of flexural-torsional buckling and demonstrates how to design against this mode of failure. The author first explains the fundamentals of this type of buckling behavior and then summarizes results that will be of use to designers and researchers in either equation or graphical form. This approach makes the book an ideal text/reference for students in structural engineering as well as for practicing civil engineers, structural engineers, and constructional steel researchers and designers. The book begins by introducing the modern development of the theory of flexural-torsional buckling through discussions on the general concepts of equilibrium, total potential, virtual work, and buckling. It then continues with in-depth coverage of hand methods for solving buckling problems, the analysis of flexural-torsional buckling using the finite element method, and the buckling of different types of structural elements and frames composed of various elastic materials. Other topics addressed include the design and inelastic buckling of steel members. The book's final chapter considers a collection of special topics.
The author offers practical coverage of vibration stresses and stress-induced displacements, isolation of sensitive components, and evaluation of elastic instability, fatigue and fracture as potential failure modes that arise in mechanical designs and aerospace. The approach taken is particularly useful in the early design stage - the physical problem is defined via known parameters, and a methodology is given for determining the unknown quantities and relating them to specified limiting values and failure modes to obtain an acceptable design. Many of the calculations can be performed on a PC or programmable calculator.
Materials of micro-/nanometer dimensions have aroused remarkable interest, motivated by the diverse utility of unconventional mechanical and electronic properties distinguished from the bulk counterpart and various industrial applications such as electronic/optic devices and MEMS/NEMS. The size of their elements is now, ultimately, approaching nanometer and atomic scales. Since the conventional theory of "fracture mechanics" is based on the continuum-body approximation, its applicability to the nanoscale components is questionable owing to the discreteness of atoms. Moreover, for describing the fracture behavior of atomic components, it is necessary to understand not only the mechanical parameters (e.g., stress and strain) but also the fracture criterion in the atomic scale. This book systematically provides recent understanding of unusual fracture behaviors in nano/atomic elements (nanofilms, nanowires, etc.) and focuses on the critical initiation and propagation of interface crack and the mechanical instability criteria of atomic structures through the introduction of state-of-the-art experimental and theoretical techniques. It covers the fundamentals and the applicability of top-down (conventional fracture mechanics to nanoscale) and bottom-up (atomistic mechanics, including quantum mechanical effects) concepts. This second edition of Fracture Nanomechanics newly includes dramatic advances in unconventional fracture mechanics in nanofilms, extraordinary fatigue mechanics and mechanisms in nanometals, and a new area of multiphysics properties in nanoelements.

This volume constitutes the Proceedings of the IUTAM Symposium on "Analytical and Computational Fracture Mechanics of Non-homogeneous Materials," held in Cardiff from 18th to 22nd June 2001. The Symposium was convened to address and place on record topical issues in analytical and computational aspects of the fracture of non-homogeneous materials as they are approached by specialists in mechanics, materials science and related fields. The expertise represented in the Symposium was accordingly very wide, and many of the world's greatest authorities in their respective fields participated. Given the extensive range and scale of non-homogeneous materials, it had to be focussed to enhance the quality and impact of the Symposium. The range of non-homogeneous materials was limited to those that are inhomogeneous at the macroscopic level and/or exhibit strain softening. The issues of micro to macro scaling were not excluded even within this restricted range which covered materials such as rock, concrete, ceramics and composites on the one hand, and, on the other, those metallic materials whose ductile fracture is strongly influenced by the presence of inhomogeneities. The Symposium remained focussed on fundamental research issues of practical significance. These issues have many common features among seemingly disparate non-homogeneous materials.

A complete and comprehensive theory of failure is developed for homogeneous and isotropic materials. The full range of materials types are covered from very ductile metals to extremely brittle glasses and minerals. Two failure properties suffice to predict the general failure conditions under all states of stress. With this foundation to build upon, many other aspects of failure are also treated, such as extensions to anisotropic fiber composites, cumulative damage, creep and fatigue, and microscale and nanoscale approaches to failure.
Intended for engineers, researchers, and graduate students dealing with materials science, structural design, and nondestructive testing and evaluation, this book represents a continuation of the author's "Fracture Mechanics" (1997). It will appeal to a variety of audiences: The discussion of design codes and procedures will be of use to practicing engineers, particularly in the nuclear, aerospace, and pipeline industries; the extensive bibliography and discussion of recent results will make it a useful reference for academic researchers; and graduate students will find the clear explanations and worked examples useful for learning the field. The book begins with a general treatment of fracture mechanics in terms of material properties and loading and provides up-to-date reviews of the ductile-britttle transition in steels and of methods for analyzing the risk of fracture. It then discusses the dynamics of fracture and creep in homogeneous and isotropic media, including discussions of high-loading-rate characteristics, the behavior of stationary cracks in elastic media under stress, and the propagation of cracks in elastic media. This is followed by an analysis of creep and crack initiation and propagation, describing, for example, the morphology and incubation times of crack initiation and growth and the effects of high temperatures. The book concludes with treatments of cycling deformation and fatigue, creep-fatigue fractures, and crack initiation and propagation. Problems at the end of each chapter serve to reinforce and test the student's knowledge and to extend some of the discussions in the text. Solutions to half of the problems are provided.
The book presents twelve state of the art contributions in the field of numerical modeling of materials subjected to large strain, high strain rates, large pressure and high stress triaxialities, organized into two sections. The first part is focused on high strain rate-high pressures such as those occurring in impact dynamics and shock compression related phenomena, dealing with material response identification, advanced modeling incorporating microstructure and damage, stress waves propagation in solids and structures response under impact. The latter part is focused on large strain-low strain rates applications such as those occurring in technological material processing, dealing with microstructure and texture evolution, material response at elevated temperatures, structural behavior under large strain and multi axial state of stress.
A Rock between Two Rivers is the story of a man coming to terms with the environmental legacy of his family’s ranch in Dimmitt County, Texas, and reckoning with the birthright he’ll leave for the generations who follow. What began for Hugh Fitzsimons as a mission to expose local ecological hazards from hydraulic fracking has turned into a lifelong ache to understand the more complicated story of how his family changed the land inherited from his grandfather, and deeper still, how the land irrevocably changed the family. Water is the lens through which this fifth-generation rancher tells his story. While the discovery of oil in this part of Texas fueled the region's growth, water has the upper hand, determining where people live and how they make their living. Agriculture, ranching, drilling for oil, and now fracking all require water, with each pursuit requiring more and more but giving back less and less to the communities they’ve helped enrich. In A Rock between Two Rivers, Fitzsimons struggles with the inheritance he wants for his own children, one that considers the future consequences of our actions toward the land we are born to and owns the broader threats to our natural resources that loom in the near distance. Interweaving a family narrative of a life built on the U.S.-Mexico border and the history of European colonization with its brutal consequences on the land and indigenous peoples, Fitzsimons explores how our attitudes toward this precious resource have changed alongside our relationship to the places we call home.

The International Conference on Fracture Mechanics in Engineering Applica tion convened at the r ational Aeronautical Laboratory (NAL) in Bangalore, India, March 26-30, 1979, with the presence of approximately 400 scientists and engi neers. The participants included individuals from all parts of India, United States of America, United Kingdom, Japan, Holland, France, Hong Kong, Korea, Sweden and Poland. The Conference was organized jointly by NAL, Bangalore;and Lehigh University, USA. Various organizations in India have also supported the Conference most generously. Professor S. Dhawan, Director of the Indian Institute of Science and Secre tary of Department of Space, delivered the inaugural speech. He said that the advance of science was the precondition of the development and survival of human society in the modern world. "It is true that in recent times, science and tech nology - and their practitioners - have been subjected to much public scrutiny, debate and severe criticism." On the other hand, the depletion of non-renewable resources, degradation of the natural environment and a host of other problems had been laid at the door of technology and science. One cannot deny that funda mental advances in the physics and chemistry of the structure of matter had led to spectacular engineering progress. Advanced technologies like nuclear energy and space exploration were but expression of the central role of computors, elec tronics, optics, polymers, etc., and all of these were heavily dependent on the successful application of material science and technology."
This International Conference on Analytical and Experimental Fracture Me chanics was organized jointly by the Centro Sperimentale Metallurgico, S. p. A. , Lehigh University and Italsider S. p. A. It took place at the Hotel Midas Palace in Rome, Italy, during 23-27 June, 1980. There were more than 150 attendees from 19 different countries: Australia, Austria, Belgium, Canada, People's Re public of China, Czechoslovakia, Finland, Federal Republic of Germany, Hungary, Israel, Italy, Japan, The Netherlands, Poland, Switzerland, Turkey, UK, USA and USSR. Dr. G. M. Costa from Finsider officially opened the Conference and gave the Welcome Address. More than 70 technical papers were presented at three con current sessions. There were six plenary lectures that helped to integrate the diverse efforts, e. g. , analytical fracture mechanics, testing methods, metallur gical effects, corrosion fatigue, dynamic crack propagation and weldments of in dividual researchers. In addition to providing an overall view of the current status of fracture mechanics technology, particular emphasis was given to methods of controlling fracture in gas pipeline structures. The members of the Organizing Committee made a special effort to organize a panel discussion on the application of fracture mechanics technology to the safe design of large diameter pipelines. Dr. Michele Civallero from Italsider and Professor George C. Sih from Lehigh University served as panel Co-Chairmen and delivered survey lectures to stimulate questions from the audience.
Fatigue and Fracture Reliability Engineering is an attempt to present an integrated and unified approach to reliability determination of fatigue and fracture behaviour, incorporating probability, statistics and other related areas. A series of original and practical approaches, are suggested in Fatigue and Fracture Reliability Engineering, including new techniques in determining fatigue and fracture performances. It also carries out an investigation into static and fatigue properties, and into the failure mechanisms of unnotched and notched CFR composite laminates with different lay-ups to optimize the stacking sequence effect. Further benefits include: a novel convergence-divergence counting procedure to extract all load cycles from a load history of divergence-convergence waves; practical scatter factor formulae to determine the safe fatigue crack initiation and propagation lives from the results of a single full-scale test of a complete structure; and a nonlinear differential kinetic model for describing the dynamical behaviour of an atom at a fatigue crack tip. Fatigue and Fracture Reliability Engineering is intended for practising engineers in marine, civil construction, aerospace, offshore, automotive and chemical industries. It is also useful reading for researchers on doctoral programmes, and is appropriate for advanced undergraduate and postgraduate programmes in any mechanically-oriented engineering discipline. |
