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.

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.
