The authors’ enthusiasm and dedication to the subject matter are clearly evident. I find the book to be not only an excellent introduction to structural characterization, but also a valuable introduction to the world of the working crystallographer. The text is rich in references to internet resources, software, literature, organizations, databases, and institutions that x-ray researchers employ routinely. As a class text the book could be used in an introductory course for third or fourth year undergraduates in materials science, chemistry, physics, or geochemistry. The detailed structural treatments may be too much for the typical introductory x-ray diffraction course, but students would be adding a valuable text for future reference to their libraries. The sections are also ideal for more advanced coursework at the graduate level. Beyond the classroom, any researcher desiring structural information on materials would benefit from this book.” - Materials Today, July/August 2004 Amazon.com readers: http://www.amazon.com/Fundamentals-Diffraction-Structural-Characterization-Materials/dp/0387241477/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1229536007&sr=8-1Table of ContentsFundamentals of Crystalline State and Crystal Lattice.- Finite Symmetry Elements and Crystallographic Point Groups.- Infinite Symmetry Elements and Crystallographic Space Groups.- Formalization of Symmetry.- Nonconventional Symmetry.- Properties, Sources, and Detection of Radiation.- Fundamentals of Diffraction.- The Powder Diffraction Pattern.- Structure Factor.- Solving the Crystal Structure.- Powder Diffractometry.- Collecting Quality Powder Diffraction Data.- Preliminary Data Processing and Phase Analysis.- Determination and Refinement of the Unit Cell.- Solving Crystal Structure from Powder Diffraction Data.- Crystal Structure of LaNi4.85Sn0.15.- Crystal Structure of CeRhGe3.- Crystal Structure of Nd5Si4.- Empirical Methods of Solving Crystal Structures.- Crystal Structure of NiMnO2(OH).- Crystal Structure of ,i.tma V3O71.- Crystal Structure of ma2Mo7O221.- Crystal Structure of Mn7(OH)3(VO4)41.- Crystal Structure of FePO4.- Crystal Structure of Acetaminophen, C8H9NO2.

John Wiley & Sons Inc Structural Reliability Analysis and Prediction
Book SynopsisStructural Reliability Analysis and Prediction, Third Edition is a textbook which addresses the important issue of predicting the safety of structures at the design stage and also the safety of existing, perhaps deteriorating structures. Attention is focused on the development and definition of limit states such as serviceability and ultimate strength, the definition of failure and the various models which might be used to describe strength and loading. This book emphasises concepts and applications, built up from basic principles and avoids undue mathematical rigour. It presents an accessible and unified account of the theory and techniques for the analysis of the reliability of engineering structures using probability theory. This new edition has been updated to cover new developments and applications and a new chapter is included which covers structural optimization in the context of reliability analysis. New examples and end of chapter problems are also now includeTable of ContentsPreface xv Preface to the Second Edition xvii Preface to the First Edition xviii Acknowledgements xx 1 Measures of

Taylor & Francis Ltd Durability of Industrial Composites
Book SynopsisDurability of Industrial Composites offers numerical and quantitative solutions to long-term composite failures that are useful to practicing engineers, researchers, and students. All modes of laminate long-term failure are contemplated, with resin toughness and environmental conditions considered. The book develops a simple unified equation to compute the load-dependent durability of laminates under the simultaneous action of cyclic and static loads. The load-independent durability and residual life of equipment immersed in corrosive chemicals are also discussed. The book presents a full discussion of the elusive strain-corrosion mode of failure as well as a complete solution to the durability issue of underground sanitation pipes. The currently accepted durability parameters of HDB, Sb and Sc are discarded as incorrect and replaced with the appropriate threshold parameters. The entirely new concept of the anomalous failure is fully discussed and solved. The Table of ContentsPart 1: Computation of Total Strains. Chapter 1. Ply Properties. Chapter 2. Laminate Circularity.

Operator Control of the ElecTrade Review“There is no other single volume that covers as much theory and practice of SEM or X-ray microanalysis as Scanning Electron Microscopy and X-ray Microanalysis, 3rd Edition does. It is clearly written ... well organized. ... This is a reference text that no SEM or EPMA laboratory should be without.” (Thomas J. Wilson, Scanning, Vol. 27 (4), July/August, 2005) “As the authors pointed out, the number of equations in the book is kept to a minimum, and important conceptions are also explained in a qualitative manner. A lot of very distinct images and schematic drawings make for a very interesting book and help readers who study scanning electron microscopy and X-ray microanalysis. The principal application and sample preparation given in this book are suitable for undergraduate students and technicians learning SEEM and EDS/WDS analyses. It is an excellent textbook for graduate students, and an outstanding reference for engineers, physical, and biological scientists.” (Microscopy and Microanalysis, Vol. 9 (5), October, 2003)Table of Contents1.

Nova Science Publishers Inc Organic Solar Cells: Advances in Research &
Book SynopsisThe last two decades have seen unprecedented research progress made in the fabrication and testing of organic solar cell (OSC) devices due to, among other things, rapid growth of interest in the development of organic materials for photovoltaic applications, the ease of processing, and the prospect of achieving high power conversion efficiency (PCE) cost effectively. The effects of impurity doping at the ppm level in photovoltaic organic semiconductors, including: (i) Seven-nines purification of organic semiconductors, (ii) pn-control of single and co-deposited organic semiconductors by impurity doping, (iii) ionisation sensitisation of doping showing the doping efficiency of 100%, (iv) ppm-doping effects in the simplest n+p-homojunction organic photovoltaic cells, and (v) the Hall effect of bulk-doped organic single crystals, are discussed in Chapter One. In Chapter Two the fabrication and characterisation of perovskite-type solar cells are reviewed and summarised such as CH3NH3PbI3, [HC(NH2)2]PbI3, and CsSnI3, which are expected for solar cell materials. Chapter Three proposes an experimental method to tailor SDE and optimise the power conversion efficiency (PCE), based on the electrical transport curve. Chapter Four provides a brief history of organic photovoltaic cell devices, factors limiting stability and power conversion efficiency, fundamental parameters that have been reported to improve the general performance of the devices, and recent developments in organic solar cell devices.

Nova Science Publishers Inc Fracture Mechanics: Theory, Applications &
Book SynopsisClassical fracture mechanics that emerged during the 1920s has gained popularity via LEFM from the 1940s to the 1960s. The principles of classical fracture mechanics evolved from experimental observation of the behaviour of glass that contains pre-existing cracks and is largely supported by physical reasoning. Chapter One presents a robust analysis of problems encountered in the field of pipeline networks and boiler components as a result of structural imperfection. Chapter Two deals with an analytical model of cracking, which is induced by thermal stresses in a porous multi-particle-matrix system. This system consists of spherical pores and isotropic spherical particles, which are both periodically distributed in an isotropic infinite matrix. Chapter Three reports on an analytical model of cracking in a multi-particle matrix system with isotropic whiskers, which are periodically distributed in an isotropic infinite matrix.

A S M International ISTFA 2021: Conference Proceedings from the 47th
Book SynopsisThe theme for the 2021 conference was System-in-Package (SiP) technology. Papers include discussions on board and system level failure analysis; detecting counterfeit microelectronics; emerging failure analysis techniques and concepts; future challenges of failure analysis; scanning probe analysis; hardware attacks, security, and reverse engineering; microscopy and material characterization; nanoprobing and electrical characterization; and more.In the 21st century, the electronic market will be driven by consumers with demands of immediate entertainment, fast access to information, and communications anywhere in a personalized fashion and at affordable prices. The new challenge is not how many transistors can be built on a single chip, as in System-on-Chip (SoC), but rather how to integrate diverse circuits together predictably, harmoniously, and cost effectively. Instead of getting twice the transistors for the same cost as Moore's Law predicted in the past 50 years, the goal of SiP is to obtain the same number of transistors for half the cost within less than half the time to market.

World Scientific Europe Ltd Wear In Advanced Engineering Applications And
Book SynopsisWear is one of the main reasons mechanical components and materials become inoperable, rendering enormous costs to society over time. Estimating wear allows engineers to predict the useful life of modern mechanical elements, reduce the costs of inoperability, or obtain optimal designs (i.e. selecting proper materials, shapes, and surface finishing according to mechanical conditions and durability) to reduce the impact of wear.Wear in Advanced Engineering Applications and Materials presents recent computational and practical research studying damage and wear in advanced engineering applications and materials. As such, this book covers numerical formulations based on the finite element method (FEM) — and the boundary element method (BEM) — as well as theoretical and experimental research to predict the wear response or life-limiting failure of engineering applications.

ISTE Ltd and John Wiley & Sons Inc Mechanical Vibration and Shock Analysis,
Book SynopsisThis volume considers the shock response spectrum, its various definitions, properties and the assumptions involved in its calculation. In developing the practical application of these concepts, the forms of shock most often used with test facilities are presented together with their characteristics and indications of how to establish test configurations comparable with those in the real, measured environment. This is followed by a demonstration of how to meet these specifications using standard laboratory equipment – shock machines, electrodynamic exciters driven by a time signal or a response spectrum – with a discussion on the limitations, advantages and disadvantages of each method.Table of ContentsForeword to Series xiii Introduction xvii List of Symbols xix Chapter 1.

Book SynopsisThe vast majority of vibrations encountered in the real environment are random in nature. Such vibrations are intrinsically complicated and this volume describes the process that enables us to simplify the required analysis, along with the analysis of the signal in the frequency domain. The power spectrum density is also defined, together with the requisite precautions to be taken in its calculations as well as the processes (windowing, overlapping) necessary to obtain improved results. An additional complementary method – the analysis of statistical properties of the time signal – is also described. This enables the distribution law of the maxima of a random Gaussian signal to be determined and simplifies the calculation of fatigue damage by avoiding direct peak counting.Table of ContentsForeword

Book SynopsisFatigue damage in a system with one degree of freedom is one of the two criteria applied when comparing the severity of vibratory environments. The same criterion is also used for a specification representing the effects produced by the set of vibrations imposed in a real environment. In this volume, which is devoted to the calculation of fatigue damage, Christian Lalanne explores the hypotheses adopted to describe the behavior of material affected by fatigue and the laws of fatigue accumulation. The author also considers the methods for counting response peaks, which are used to establish the histogram when it is not possible to use the probability density of the peaks obtained with a Gaussian signal. The expressions for mean damage and its standard deviation are established and other hypotheses are tested.Table of ContentsForeword to Series xiii Introduction xvii List of Symbols xix Chapter 1.

ISTE Ltd and John Wiley & Sons Inc Micromechanics of Fracture and Damage
Book SynopsisThis book deals with the mechanics and physics of fractures at various scales. Based on advanced continuum mechanics of heterogeneous media, it develops a rigorous mathematical framework for single macrocrack problems as well as for the effective properties of microcracked materials. In both cases, two geometrical models of cracks are examined and discussed: the idealized representation of the crack as two parallel faces (the Griffith crack model), and the representation of a crack as a flat elliptic or ellipsoidal cavity (the Eshelby inhomogeneity problem). The book is composed of two parts: The first part deals with solutions to 2D and 3D problems involving a single crack in linear elasticity. Elementary solutions of cracks problems in the different modes are fully worked. Various mathematical techniques are presented, including Neuber-Papkovitch displacement potentials, complex analysis with conformal mapping and Eshelby-based solutions. The second part is devoted to continuum micromechanics approaches of microcracked materials in relation to methods and results presented in the first part. Various estimates and bounds of the effective elastic properties are presented. They are considered for the formulation and application of continuum micromechanics-based damage models.

John Wiley & Sons Inc Reliability and Risk Assessment
Book SynopsisRisk assessment and risk analysis are now firmly fixed in the engineer’s lexicon. Every engineering project, contract, piece of equipment and design requires this discipline by law. Reliability is the other key element in the mix for smooth running engineering projects and operations. In the modern industrial era, economic factors have resulted in the construction and operation of larger and more complex process plant. Accidents at these types of plants have led to notorious incidents such as Flixborough, Bhopal, Chernobyl, and Piper Alpha. Engineers are working to maximize the benefits of modern processing technology while reducing the safety risks to acceptable levels. However, each processing plant has unique problems and each must be individually assessed to identify, evaluate, and control associated hazards. The first edition of Reliability and Risk Assessment was ahead of its time. The world has caught up with Andrews and Moss and this fully revised second edition takes the analysis further and brings a more practical slant with greater and extensive use of case studies. Reliability and Risk Assessment is for professional engineers but will also prove invaluable for postgraduate students involved in reliability and risk assessment research. KEY FEATURES: Rigourous mathmatical descriptions of the most important techniques, particularly fault tree analysis and Markov methods. Practical examples of the application of these techniques to real-life problems. Self-contained chapters detail methods of reliability and risk assessment. Worked examples clarify the text and highlight salient points. Three new detailed case studies include: FMECA for a gas turbine system; in-service inspection of structural components, and a business interruption risk analysis. Table of ContentsAn introduction to reliability and risk assessment; reliability mathematics; qualitative methods; failure mode and effects criticality analysis; quantification of component failure probabilities; reliability networks; qualitative fault tree analysis; common cause failures; maintainability; Markov analysis; simulation; reliability data collection and analysis; risk assessment; in-service inspection of structural components.
