Publisher's Synopsis
In this unique book, Shchepinov and his colleagues introduce and discuss the development and application of the increasingly important technique; holographic and speckle interferometry employed in the investigation of structure and material deformation and fracture processes. The authors consider the main physical and metrological aspects of interferometry from the deformation analysis viewpoint, emphasizing the need for (and the difficulties in obtaining) high quality and accurate fringe patterns. The advantages and outstanding features of the techniques are discussed in the second part of the book and these are compared with conventional methods of experimental mechanics. The book is illustrated with numerous unique interferograms to demonstrate the various fringe patterns which must be quantitively interpreted to obtain strain and stress values with the required accuracy. All fringe patterns presented are primary sources of the corresponding displacement and strain distributions contained in the book. The results illustrate how holographic and speckle interferometry can be used for development in various scientific and applied subjects in the fields of solid and fracture mechanics. Written specifically for researchers and engineers specializing in the strength of structures and materials, this book will also serve to introduce students to the fundamentals of holographic and speckle interferometry and the way these methods can be applied in experimental mechanics.
