Damage, Fracture, and Fatigue of Ceramic-Matrix Composites
by Longbiao LiThis book focuses on the damage, fracture and fatigue of ceramic-matrix composites. It investigates tensile damage and fracture, fatigue hysteresis, and the properties of interfaces subjected to cyclic fatigue loading. Further, it predicts fatigue life at room and elevated temperatures using newly developed damage models and methods, and it analyzes and compares damage, fracture and fatigue behavior of different fiber performs: unidirectional, cross-ply, 2D and 2.5D woven. The developed models and methods can be used to predict the damage and lifetime of ceramic-matrix composites during applications on hot section components.Ceramic-matrix composites (CMCs) are high-temperature structural materials with the significant advantages of high specific strength, high specific modulus, high temperature resistance and good thermal stability, which play a crucial role in the development of high thrust weight ratio aero engines. The critical nature of the application of these advanced materials makes comprehensive characterization a necessity, and as such this book provides designers with essential information pertaining not only to the strength of the materials, but also to their fatigue and damage characteristics.
Damage Growth in Aerospace Composites (Springer Aerospace Technology)
by Aniello RiccioThis book presents novel methods for the simulation of damage evolution in aerospace composites that will assist in predicting damage onset and growth and thus foster less conservative designs which realize the promised economic benefits of composite materials. The presented integrated numerical/experimental methodologies are capable of taking into account the presence of damage and its evolution in composite structures from the early phases of the design (conceptual design) through to the detailed finite element method analysis and verification phase. The book is based on the GARTEUR Research Project AG-32, which ran from 2007 to 2012, and documents the main results of that project. In addition, the state of the art in European projects on damage evolution in composites is reviewed. While the high specific strength and stiffness of composite materials make them suitable for aerospace structures, their sensitivity to damage means that designing with composites is a challenging task. The new approaches described here will prove invaluable in meeting that challenge.
Damage Mechanics in Metal Forming: Advanced Modeling and Numerical Simulation (Wiley-iste Ser.)
by Khemais SaanouniThe aim of this book is to summarize the current most effective methods for modeling, simulating, and optimizing metal forming processes, and to present the main features of new, innovative methods currently being developed which will no doubt be the industrial tools of tomorrow. It discusses damage (or defect) prediction in virtual metal forming, using advanced multiphysical and multiscale fully coupled constitutive equations. Theoretical formulation, numerical aspects as well as application to various sheet and bulk metal forming are presented in detail.Virtual metal forming is nowadays inescapable when looking to optimize numerically various metal forming processes in order to design advanced mechanical components. To do this, highly predictive constitutive equations accounting for the full coupling between various physical phenomena at various scales under large deformation including the ductile damage occurrence are required. In addition, fully 3D adaptive numerical methods related to time and space discretization are required in order to solve accurately the associated initial and boundary value problems. This book focuses on these two main and complementary aspects with application to a wide range of metal forming and machining processes. Contents 1. Elements of Continuum Mechanics and Thermodynamics.2. Thermomechanically-Consistent Modeling of the Metals Behavior with Ductile Damage.3. Numerical Methods for Solving Metal Forming Problems.4. Application to Virtual Metal Forming.

Damage Tolerance of Metallic Aircraft Structures
by Sérgio M. Tavares Paulo M. de CastroThis book provides a state-of-the-art review of the fail-safe and damage tolerance approaches, allowing weight savings and increasing aircraft reliability and structural integrity.The application of the damage tolerance approach requires extensive know-how of the fatigue and fracture properties, corrosion strength, potential failure modes and non-destructive inspection techniques, particularly minimum detectable defect and inspection intervals. In parallel, engineering practice involving damage tolerance requires numerical techniques for stress analysis of cracked structures. These evolved from basic mode I evaluations using rough finite element approaches, to current 3D modeling based on energetic approaches as the VCCT, or simulation of joining processes. This book provides a concise introduction to this subject.

The Dams of Western San Diego County
by John MartinThe unreliability of the San Diego River compelled the Franciscan fathers to construct the area's first dam in 1813 to conserve drinking and irrigation water for the Mission San Diego de Alcal". This water-driven circumstance continued and expanded in the ensuing American era. Lacking a reliable water source at the turn of the 20th century, San Diego County was destined to experience modest growth. The region's semiarid conditions, cyclical droughts, and existing river systems determined that the only effective way to maintain a ready water supply was to conserve runoff and river floodwaters behind dam-created reservoirs. Between 1888 and 1934, private and municipal interests constructed a series of massive structures that made San Diego County the dam-building center of the world. The county featured some of America's first multiple arch dams and earliest hydraulic fill dams. Into the mid-1940s, dammed reservoirs remained the principle water source for county consumers and made the municipal expansion of the city of San Diego possible.
Dams Safety and Society
by Ljiljana Spasic-GrilThis book addresses current international practices applied for dam safety assessments by looking at a portfolio of dam safety projects in various developing countries (Armenia, Georgia, Tajikistan, Mauritius, Madagascar, Sri Lanka, Myanmar and Vietnam) spread across three continents (Europe, Africa and Asia). Safety assessment involved the review of 134 existing dams and comparison with the best international practices. A large part of dam safety assessment involves understanding of dam hazards, standards applied in the design and maintenance, as well as expectation and social circumstances under which the dams have been designed and constructed in a particular country. For example, standards for design floods, ground investigation, selection of design soil parameters and design earthquakes etc. used are often either non-existent or inadequate, which could lead to an unsafe design. If there are no standards to be applied in dam design and construction, consultants are often under pressure from clients to come up with minimalistic investigation and designs, which, after a few years after dam construction, show signs of deficiencies. Very often countries have no regulations and standards for requirements that should cover the maintenance and operation of dams. The book also describes the Portfolio Risk Assessment of Dams, which can be used as a tool by clients and the funding agencies to identify priority assessment and rehabilitation projects that consider societal and economic losses. It also demonstrates how the implementation of Emergency Preparedness Planning could significantlyreduce the number of people at risk. This book aims to help clients, consultants and funding agencies which are engaged in dam safety assessment projects in developing countries to focus on issues that are based on past lessons learnt.
Dance Lexicon in Shakespeare and His Contemporaries: A Corpus Based Approach (Studies in Performance and Early Modern Drama)
by Fabio CiambellaThis book provides a thorough analysis of terpsichorean lexis in Renaissance drama. Besides considering not only the Shakespearean canon but also the Bard’s contemporaries (e.g., dramatists as John Marston and Ben Jonson among the most refined Renaissance dance aficionados), the originality of this volume is highlighted in both its methodology and structure. As far as methods of analysis are concerned, corpora such as the VEP Early Modern Drama collection and EEBO, and corpus analysis tools such as #LancsBox are used in order to offer the widest range of examples possible from early modern plays and provide co-textual references for each dance. Examples from Renaissance playwrights are fundamental for the analysis of connotative meanings of the dances listed and their performative, poetic and metaphoric role in sixteenth- and seventeenth-century drama. This study will be of great interest to Renaissance researchers, lexicographers and dance historians.

Dance Notations and Robot Motion (Springer Tracts in Advanced Robotics #111)
by Jean-Paul Laumond Naoko AbeHow and why to write a movement? Who is the writer? Who is the reader? They may be choreographers working with dancers. They may be roboticists programming robots. They may be artists designing cartoons in computer animation. In all such fields the purpose is to express an intention about a dance, a specific motion or an action to perform, in terms of intelligible sequences of elementary movements, as a music score that would be devoted to motion representation. Unfortunately there is no universal language to write a motion. Motion languages live together in a Babel tower populated by biomechanists, dance notators, neuroscientists, computer scientists, choreographers, roboticists. Each community handles its own concepts and speaks its own language. The book accounts for this diversity. Its origin is a unique workshop held at LAAS-CNRS in Toulouse in 2014. Worldwide representatives of various communities met there. Their challenge was to reach a mutual understanding allowing a choreographer to access robotics concepts, or a computer scientist to understand the subtleties of dance notation. The liveliness of this multidisciplinary meeting is reflected by the book thank to the willingness of authors to share their own experiences with others.
The Dancing Bees: Karl von Frisch and the Discovery of the Honeybee Language
by Tania MunzWe think of bees as being among the busiest workers in the garden, admiring them for their productivity. But amid their buzzing, they are also great communicators--and unusual dancers. As Karl von Frisch (1886-1982) discovered during World War II, bees communicate the location of food sources to each other through complex circle and waggle dances. For centuries, beekeepers had observed these curious movements in hives, and others had speculated about the possibility of a bee language used to manage the work of the hive. But it took von Frisch to determine that the bees' dances communicated precise information about the distance and direction of food sources. As Tania Munz shows in this exploration of von Frisch's life and research, this important discovery came amid the tense circumstances of the Third Reich. The Dancing Bees draws on previously unexplored archival sources in order to reveal von Frisch's full story, including how the Nazi government in 1940 determined that he was one-quarter Jewish, revoked his teaching privileges, and sought to prevent him from working altogether until circumstances intervened. In the 1940s, bee populations throughout Europe were facing the devastating effects of a plague (just as they are today), and because the bees were essential to the pollination of crops, von Frisch's research was deemed critical to maintaining the food supply of a nation at war. The bees, as von Frisch put it years later, saved his life. Munz not only explores von Frisch's complicated career in the Third Reich, she looks closely at the legacy of his work and the later debates about the significance of the bee language and the science of animal communication. This first in-depth biography of von Frisch paints a complex and nuanced portrait of a scientist at work under Nazi rule. The Dancing Bees will be welcomed by anyone seeking to better understand not only this chapter of the history of science but also the peculiar waggles of our garden visitors.
Dancing Naked in the Mind Field
by Kary MullisHere are the outrageous ideas and extraordinary adventures of the world's most eccentric and outspoken Nobel Prize-winning scientist. Awarded the Nobel Prize in chemistry in 1993, Kary Mullis has frequently been at odds with the scientific establishment. Legendary for his invention of the polymerase chain reaction (PCR), which redefined the world of DNA and genetics, Mullis is also an accomplished surfer, a veteran of Berkeley in the sixties, and perhaps the only Nobel laureate to describe a possible encounter with aliens. A scientist of boundless curiosity who refuses to accept any proposition based on secondhand or hearsay evidence, he is brilliant, funny, provocative, and charismatic. InDancing Naked in the Mind FieldMullis writes with passion and humor about a wide range of subjects: from the scientific method to parapsychology, from poisonous spiders to the HIV virus and AIDS, from global warming to astrology, from the O. J. Simpson trial to how you can turn a light bulb on with your mind. A multidimensional playland of ideas, this book challenges us to question the authority of scientific dogma even as it reveals the workings of an uncannily original scientific mind.
Dancing with Bees: A Journey Back to Nature
by Brigit Strawbridge HowardA naturalist’s passionate dive into the world of bees of all stripes--what she has learned about them, and what we can learn from them Brigit Strawbridge Howard was shocked the day she realised she knew more about the French Revolution than she did about her native trees. And birds. And wildflowers. And bees. The thought stopped her—quite literally—in her tracks. But that day was also the start of a journey, one filled with silver birches and hairy-footed flower bees, skylarks, and rosebay willow herb, and the joy that comes with deepening one’s relationship with place. Dancing with Bees is Strawbridge Howard’s charming and eloquent account of a return to noticing, to rediscovering a perspective on the world that had somehow been lost to her for decades and to reconnecting with the natural world. With special care and attention to the plight of pollinators, including honeybees, bumblebees, and solitary bees, and what we can do to help them, Strawbridge Howard shares fascinating details of the lives of flora and fauna that have filled her days with ever-increasing wonder and delight.
