Moiré Fringes in Strain Analysis provides a comprehensive coverage of the measurement of strains in deformed bodies and engineering structures. The title details the methods and techniques in strain analysis using the moiré fringe phenomenon. The text first covers the general theory, and then proceeds to tackling the moiré patterns. Next the selection deals with the applications of line gratings to two-dimensional strain measurement. The text also talks about surface topology by moiré patterns, along with the applications of moiré methods to dynamic problems and curved surfaces. The ninth chapter discusses moiré extensometers, while the tenth chapter tackles the precision and influence of grating defects. The remaining chapters detail the technological information on reproduction techniques of gratings and the evaluation of moiré methods. The book will be of great use to students, practitioners, and researchers of materials engineering and pure and applied mathematics.

Moiré Fringes in Strain Analysis provides a comprehensive description of the entire spectrum of techniques and methods using the moiré fringe phenomenon for the measurement of strains in engineering structures and in deformed bodies. This book presents several examples of applications of each technique to particular metrological problems. Organized into 12 chapters, this book begins with an overview of the interference fringes between two beams of monochromatic light. This text then discusses the theory of moiré patterns developed by various types of gratings based on the indicial representation method. Other chapters consider the experimental and theoretical investigation of the properties of moiré fringes that was primarily confined to moiré fringes formed by the interference of two-line gratings. This book discusses as well the major requisite for the application of moiré methods in the field of strain analysis. The final chapter deals with the advantages of the moiré methods. This book is a valuable resource for engineers, students and researchers.

Fundamental measurement problems in engineering, mechanics, manufacturing, and physics are now being solved by powerful optical methods. This book presents a lucid, up-to-date discussion of these optical methods. Beginning from a firm base in modern optics, the book proceeds through relevant theory of interference and diffraction and integrates this theory with descriptions of laboratory techniques and apparatus. Among the techniques discussed are classical interferometry, photoelasticity, geometric moire, spatial filtering, moire interferometry, holography, holographic interferometry, laser speckle interferometry, and video-based speckle methods. By providing a firm base in the physical principles and at the same time allowing the reader to perform meaningful experiments related to the topic being studied, the book offers a unique user-oriented approach that will appeal to students, researchers and practising engineers.

Experimental Stress Analysis deals with different aspects of stress analysis, highlighting basic and advanced concepts, with a separate chapter on aircraft structures. The inclusion of a large number of figures, tables, and solved problems ensure a

This book contains chapters on nanocomposites for engineering hard materials for high performance aircraft, rocket and automobile use, using laser pulses to form metal coatings on glass and quartz, and also tungsten carbide-cobalt nanoparticles using high voltage discharges. A major section of this book is largely devoted to chapters outlining and applying analytic methods needed for studies of nanocomposites. As such, this book will serve as good resource for such analytic methods.

The Army Materials and Mechanics Research Center of Water town, Massachusetts in cooperation with the Materials Science Group of the Department of Chemical Engineering and Materials Science of Syracuse University has conducted the Sagamore Army Materials Research Conference since 1954. The main purpose of these conferences has been to gather together over 150 scientists and engineers from academic institutions, industry and government who are uniquely qualified to explore in depth a subject of importance to the Department of Defense, the Army and the scientific community. This volume NONDESTRUCTIVE EVALUATION OF MATERIALS, addresses the areas of x-ray, ultrasonics and other methods of nondestructive testing. We wish to acknowledge the dedicated assistance of Joseph M. Bernier of the Army Materials and Mechanics Research Center and Helen Brown DeMascio of Syracuse University throughout the stages of the conference planning and finally the publication of this book. Their help is deeply appreciated. Syracuse University Syracuse, New York The Editors Contents SESSION I X-RAY S. Heissman, Moderator H. K. Herglotz, Moderator 1.

Optical Methods of Measurement: Wholefield Techniques, Second Edition provides a comprehensive collection of wholefield optical measurement techniques for engineering applications. Along with the reorganization of contents, this edition includes a new chapter on optical interference, new material on nondiffracting and singular beams and their applications, and updated bibliography and additional reading sections. The book explores the propagation of laser beams, metrological applications of phase-singular beams, various detectors such as CCD and CMOS devices, and recording materials. It also covers interference, diffraction, and digital fringe pattern measurement techniques, with special emphasis on phase measurement interferometry and algorithms. The remainder of the book focuses on theory, experimental arrangements, and applications of wholefield techniques. The author discusses digital hologram interferometry, digital speckle photography, digital speckle pattern interferometry, Talbot interferometry, and holophotoelasticity. This updated book compiles the major wholefield methods of measurement in one volume. It provides a solid understanding of the techniques by describing the physics behind them. In addition, the examples given illustrate how the techniques solve measurement problems.
