Book Description
This edition has been greatly enlarged and updated to provide both scientists and engineers with a clear and comprehensive understanding of composite materials. In describing both theoretical and practical aspects of their production, properties and usage, the book crosses the borders of many disciplines. Topics covered include: fibres, matrices, laminates and interfaces; elastic deformation, stress and strain, strength, fatigue crack propagation and creep resistance; toughness and thermal properties; fatigue and deterioration under environmental conditions; fabrication and applications. Coverage has been increased to include polymeric, metallic and ceramic matrices and reinforcement in the form of long fibres, short fibres and particles. Designed primarily as a teaching text for final-year undergraduates in materials science and engineering, this book will also interest undergraduates and postgraduates in chemistry, physics, and mechanical engineering. In addition, it will be an excellent source book for academic and technological researchers on materials.

Book Description
In the 1950s the direct observation of dislocations became possible, stimulat ing the interest of many research workers in the dynamics of dislocations. This led to major contributions to the understanding of the plasticity of various crys talline materials. During this time the study of metals and alloys of fcc and hcp structures developed remarkably. In particular, the discovery of the so-called in ertial effect caused by the electron and phonon frictional forces greatly influenced the quantitative understanding of the strength of these metallic materials. Statis tical studies of dislocations moving through random arrays of point obstacles played an important role in the above advances. These topics are described in Chaps. 2-4. Metals and alloys with bcc structure have large Peierls forces compared to those with fcc structure. The reasons for the delay in studying substances with bcc structure were mostly difficulties connected with the purification techniques and with microscopic studies of the dislocation core. In the 1970s, these difficulties were largely overcome by developments in experimental techniques and computer physics. Studies of dislocations in ionic and covalent bonding materials with large Peierls forces provided infonnation about the core structures of dislocations and their electronic interactions with charged particles. These are the main subjects in Chaps. 5-7.

Book Description
For more than 100 years, congenital dislocation of the hip has been an area of concern in orthopedics. This publications on the subject are al most too numerous to count. Yet our knowledge of the basic principles of congenital hip dislocation and its management is constantly being expanded by new research. In Germanspeaking countries, Kaiser pub lished the last comprehensive textbook on congenital hip dislocation in 1958, and Schlegel followed with a comprehensive handbook in 1961. In the Angloamerican world, Coleman's monograph was pub lished in 1978, Somerville's in 1982, and Wilkinson's in 1985. In 1982 Tachdjian compiled a volume on congenital hip dislocation that con tained contributions from 44 authorities. The purpose of the present book is to provide an overview of our pre sent state of knowledge of congenital hip dislocation, covering basic principles, diagnosis, methods of closed and open treatment, and indi cations. In the process, an attempt is made to trace progress in the field from its beginnings to the present time. Many authors describe the diagnosis and treatment of congenital hip dysplasia and dislocation in terms of specific age groups. We believe it is more prudent to take an individualized approach based on arthro graphic findings and the degree of severity of pathologic changes. Less emphasis is placed here on the management of patients by age group.

Book Description
Dislocation Based Crystal Plasticity: Theory and Computation at Micron and Submicron Scale provides a comprehensive introduction to the continuum and discreteness dislocation mechanism-based theories and computational methods of crystal plasticity at the micron and submicron scale. Sections cover the fundamental concept of conventional crystal plasticity theory at the macro-scale without size effect, strain gradient crystal plasticity theory based on Taylar law dislocation, mechanism at the mesoscale, phase-field theory of crystal plasticity, computation at the submicron scale, including single crystal plasticity theory, and the discrete-continuous model of crystal plasticity with three-dimensional discrete dislocation dynamics coupling finite element method (DDD-FEM). Three kinds of plastic deformation mechanisms for submicron pillars are systematically presented. Further sections discuss dislocation nucleation and starvation at high strain rate and temperature effect for dislocation annihilation mechanism. - Covers dislocation mechanism-based crystal plasticity theory and computation at the micron and submicron scale - Presents crystal plasticity theory without size effect - Deals with the 3D discrete-continuous (3D DCM) theoretic and computational model of crystal plasticity with 3D discrete dislocation dynamics (3D DDD) coupling finite element method (FEM) - Includes discrete dislocation mechanism-based theory and computation at the submicron scale with single arm source, coating micropillar, lower cyclic loading pillars, and dislocation starvation at the submicron scale

Book Description
Dislocations deals with the main properties of dislocations, including motion, climb, and vacancies. Topics covered include the elastic theory of dislocations, imperfect dislocations, and crystal growth, along with dislocation networks, annealing, and grain boundaries. The interaction of dislocations with other defects is also discussed. This book is comprised of 17 chapters and begins with an overview of the general properties of dislocations, with emphasis on perfect and real crystals and the general case for translation dislocations. The reader is then introduced to the motion of dislocations, including glide; vacancies and interstitial atoms; dislocation climb; imperfect dislocations and surfaces of misfit; and crystal growth, including growth from a liquid phase. The next section is devoted to the more or less complex networks of dislocations that can be formed in crystals, and to the plastic properties corresponding to these arrays. The remaining chapters explore the interactions of dislocations with other crystalline defects, primarily impurity atoms. This monograph is intended for physicists, metallurgists, materials scientists, research and engineering students, and research engineers.

Book Description
The problems of the patellofemoral joint remain a challenge to the orthopaedic surgeon. In spite of many articles in scientific journals, an outstanding monograph, and several excellent textbook chapters, the patella is still an enigma in many respects. The etiology of patellar pain is controversial, and there is no completely satisfying explanation for its cause or its relationship to chondromalacia. Curiously, neither the widespread use of arthroscopy nor the advent of newer diagnostic tests such as CT scanning and magnetic resonance imaging have cast much light. Without a better understanding of why patellar disorders occur it is not surprising that there is no consensus on how to fix them. Arthros copy has contributed little except to the patient's psyche. The currently most popular surgical treatment for recurrent dislocation of the patella was first described 50 years ago. One concrete advance, albeit a small one, is a better understanding of the role of anatomical abnormalities and patellofemoral dysplasia in patellar instabilities. It gives me great pleasure that many of the contributors are, like Dr.

Book Description
This book provides a comprehensive overview of dislocation of the temporomandibular joint (TMJ), covering all relevant aspects, from aetiology and diagnosis to management. The treatment-oriented chapters describe nonsurgical, surgical and arthroscopic interventions, and the book closes by examining the role of total alloplastic reconstruction of the TMJ in patients with chronic jaw joint dislocation. Each chapter commences with a summary of key points and the clearly written text is supported by numerous clinical photographs, as well as by videos to which the reader will have online access. All of the authors are recognized experts in the topics that they discuss. Dislocation of the TMJ constitutes a medical emergency since prompt treatment is required in order to prevent the harmful sequelae that may arise once spasm of the muscles of mastication has become established, preventing return of the condyle into the glenoid fossa. If the condition is left untreated, radical corrective surgery may be required to restore jaw function and eliminate pain. In presenting state of the art knowledge on TMJ dislocation, this book will be of value for all involved in the management of the condition.

Book Description
Renos K. Papadopoulos clearly and sensitively explores the experiences of people who reluctantly abandon their homes, searching for safer lives elsewhere, and provides a detailed guide to the complex experiences of involuntary dislocation. Involuntary Dislocation: Home, Trauma, Resilience, and Adversity-Activated Development identifies involuntary dislocation as a distinct phenomenon, challenging existing assumptions and established positions, and explores its linguistic, historical, and cultural contexts. Papadopoulos elaborates on key themes including home, identity, nostalgic disorientation, the victim, and trauma, providing an in-depth understanding of each contributing factor whilst emphasising the human experience throughout. The book concludes by articulating an approach to conceptualising and working with people who have experienced adversities engendered by involuntary dislocation, and with a reflection on the language of repair and renewal. Involuntary Dislocation will be a compassionate and comprehensive guide for psychotherapists, clinical psychologists, counsellors, and other professionals working with people who have experienced displacement. It will also be important reading for anyone wishing to understand the psychosocial impact of extreme adversity.

Book Description
The dislocation is the basic building block of the crack in an elastic-plastic solid. Fracture mechanics is developed in this text from its dislocation foundation. It is the only text to do so. It is written for the graduate student and the new investigator entering the fracture field as well as the experienced scientist who has not used the dislocation approach. The dislocation mechanics needed to find the dislocation density fields of crack tip plastic zones is developed in detail. All known dislocation based solutions are given for the three types of cracks in elastic-plastic solids are given.
