Book Synopsis Holographic Interferometry in Materials Research and Fracture Mechanics by : T. D. DUDDERAR
Download or read book Holographic Interferometry in Materials Research and Fracture Mechanics written by T. D. DUDDERAR and published by . This book was released on 1972 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: HOLOGRAPHIC INTERFEROMETRY IS A NEW OPTICL METHOD FOR MEASURING DISPLACEMENT AND DEFORMATION FIELDS WHICH EXPLOITS UNIQUE PROPERTIES OF HOLOGRAPHY. SPECIFICALLY, HOLOGRAPHY PERMITS STORAGE OF A LIGHT WAVE FRONT AND ITS SUBSEQUENT RECONSTRUCTION AT ANY DESIRED TIME. AS SUCH, IT PROVIDES AN OPTICAL REPLICA OF A TEST PIECE IN A GIVEN STATE WHICH OPTICALLY INTERFERES WITH SUBSEQUENT IMAGES OF THE TEST PIECE. UNDER APPROPRIATE CONDITIONS, THE RESULTING INTERFERENCE PATTERN CAN THEN BE RELATED TO CHANGES IN POSITION AND DEFORMATION OF THE TEST PIECE. THE TECHNIQUE MAY BE ADAPTED TO THE USE OF EITHER TRANSPARENT OR OPAQUE TEST PIECES, AND WITH FAR GREATER FLEXIBILITY AND RANGE OF MEASUREMENT THAN CONVENTIONAL INTERFEROMETRY WHERE ALL SURFACES MUST BE OPTICALLY FLAT. BOTH REAL TIME AND STORED STATIC AND DYNAMIC TECHNIQUES HAVE NOW BEEN DEVELOPED AND ARE CONTINUOUSLY BEING REFINED. PROMISING AREAS FOR APPLICATION ARE IN ASSOCIATION WITH AND AS A COMPLEMENT TO PHOTO-ELASTICITY FOR STATIC AND DYNAMIC MODEL ANALYSIS, AND IN SUCH MATERIALS STUDIES AS FLAW GROWTH OR DAMAGE DETECTION IN FATIGUE AND FRACTURE MECHANICS.
Book Synopsis Holographic Interferometry in Experimental Mechanics by : Yuri I. Ostrovsky
Download or read book Holographic Interferometry in Experimental Mechanics written by Yuri I. Ostrovsky and published by Springer. This book was released on 2013-06-29 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph deals with diverse applications of holographic interferome try in experimental solid mechanics. Holographic interferometry has experienced a development of twenty years. It has enjoyed success and suffered some disappointments mainly due to early overestimation of its potential. At present, development of holo graphic interferometry is progressing primarily as a technique for quantita tive measurements. This is what motivated us to write this book - to ana lyze the quantitative methods of holographic interferometry. The fringe patterns obtained in holographic interferometry are graphi cally descriptive. In the general case, however, because they contain infor mation on the total vectors of displacement for points on the surface of a stressed body, the interpretation of these interferograms is much more complicated than in typical conventional interferometry. In addition, the high sensitivity of the method imposes new requirements on the loading of the objects under study. New approaches to designing loading fixtures are needed in many cases to ensure the desired loading conditions. The wealth of information obtained in holographic interferometry necessitates the use of modern computational mathematics. Therefore, practical implementation of the various methods of holographic interferometry must overcome sub stantial difficulties requiring adequate knowledge in diverse areas of science such as coherent optics, laser technology, mechanics, and applied mathe matics. Experimental methods play a significant role in solid mechanics.

Book Synopsis Holographic Interferometry by : Pramod K. Rastogi
Download or read book Holographic Interferometry written by Pramod K. Rastogi and published by Springer. This book was released on 2013-04-17 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Holographic Interferometry provides a valuable and up-to-date source of information in the rapidly expanding field. The eight specialists` contributions cover the principles and methods currently in use. The scope of the book has been limited to the study of opaque object and ample space has been devoted to a comprehensive treatment of the phenomena of fringe formation, with a particular emphasis on the quantitative evaluation of the holographic interference fringe patterns. The emergence of computer-aided fringe analysis and phase-shifting techniques have simplified considerably the quantative real-time measurements of object shapes and deformations. The last two chapters provide a reasonably detailedoverview of full-field holographic methods for the measurement of shapes, displacements, dervatives, difference displacements and vibrations.

Book Synopsis Strain and Stress Analysis by Holographic and Speckle Interferometry by : Valeriĭ Pavlovich Shchepinov
Download or read book Strain and Stress Analysis by Holographic and Speckle Interferometry written by Valeriĭ Pavlovich Shchepinov and published by . This book was released on 1996-05-27 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Holographic Interferometry by : Gregory R. Toker
Download or read book Holographic Interferometry written by Gregory R. Toker and published by CRC Press. This book was released on 2017-12-19 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transparent in the visible range, phase objects can be studied in the optical range using holographic interferometry. Typically, the holograms are recorded on high-resolving-power holographic photo materials, but a lower spatial resolution is sufficient for successful research in many scientific applications. Holographic Interferometry: A Mach–Zehnder Approach offers practical guidance to research scientists and engineers using Mach–Zehnder holographic interferometry methods to study phase objects in the laboratory. The Mach–Zehnder approach allows the use of standard photographic film and electronic CCD/CMOS sensors with low resolving power, making it a simpler and more affordable option for testing many types of phase objects. This book demonstrates how to use standard photographic film for the optical recording and reconstruction of Mach–Zehnder holograms. It also illustrates techniques for using CCD/CMOS cameras to digitally record Mach–Zehnder holograms/interferograms of transparent objects. Bringing together original research and information scattered throughout existing literature, this book focuses on the holographic reference beam and shearing interferometry methods. In particular, it looks at how these methods and optical schemes can be directly applied to testing aerodynamic flows, as well as to plasmas, shocks, and waves in noncoherent laser–matter interactions. Numerous reconstructed and classic interferograms, deflectograms, and Schlierengrams illustrate the material, helping readers develop and design their own optimal optical scheme and choose applicable details to apply the approach. Describing methods in a mathematically simple and accessible way, this book is also suitable for graduate students in the fields of aerospace engineering and optics, as well as those in laser, thermal, and plasma physics.
Book Synopsis Fracture mechanics of concrete: Material characterization and testing by : Alberto Carpinteri
Download or read book Fracture mechanics of concrete: Material characterization and testing written by Alberto Carpinteri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume on the mechanics of fracture of Portland cement concrete, the general theme is the connection between microstructural phenomena and macroscopic models. The issues addressed include techniques for observation over a wide range of scales, the influence of .microcracking on common measures of strength and de formability , and ultimately, the relationship between microstructural changes in concrete under load and its resistance to cracking. It is now commonly accepted that, in past attempts to force-fit the behavior of concrete into the rules of linear elastic fracture mechanics, proper attention has not been paid to scale effects. Clearly, the relationships among specimen size, crack length and opening, and characteristic material fabric dimensions have been, in comparison to their counterparts in metals, ceramics, and rocks, abused in concrete. Without a fundamental understanding of these relationships, additional testing in search of the elusive, single measure of fracture toughness has spawned additional confusion and frustration. No one is in a better position to document this observation than Professor Mindess.

Download or read book Holographic Interferometry written by W. Schumann and published by Springer. This book was released on 2013-06-29 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This small book intends to build a bridge between the aspects of Optics and of Mechanics that are involved in the application of holographie interferometry to deformation analysis of opaque bodies. As such, it follows in some way the footsteps ofthe late Prof. H. Favre, who already in 1927 proposed to use interferometry for deformation measurements (refer to his thesis "Sur une nouveHe methode optique de determination des tensions interieures"). Many a concept also originates from the research and lectures of Prof. W. Prager in continuum mechanies, Profs. D.C. Drucker and C. Mylonas in experimental mechanics, Prof. C.R. Steele in sheH theory and Prof. W. Lukosz in physieal optics. Further stimulation arose in dis cussions about holography with Profs. R. Dändliker, J. Der Hovanesian and H. Tiziani as weH as with Drs. B. Ineiehen and F.M. Mottier. The contribution of Drs. W. Wüthrich, P. Bohler and G. Teichmann must also be acknowledged, the latter more partieularly for rendering valuable assistance on the delieate points of tensor calculus as weH as in the drawing of the figures. FuH gratitude must also be expressed to those who made the publication of this book possible: Dr. D. MacAdam who openheartedly accepted it in his series, Dr. H. Lotsch and the collab orators of Springer-Verlag, Mr. P. Hagnauer who revised the original text and Mrs. L. Wehrli whose patience was tried in carefully typing the manuscript, whieh Mr. F. Dufour read over again

This book was released on 2006-04-11 with total page 673 pages. Available in PDF, EPUB and Kindle. Book excerpt: The request to organize under its patronage at Poitiers in 1998 a Symposium entitled “Advanced Optical Methods and Applications in Solid Mechanics” by the International Union of Theoretical and Applied Mechanics (I.U.T.A.M.) was well received for the following two reasons. First, for nearly 20 years no Symposium devoted to optical methods in solids had been organized. Second, recent advances in digital image processing provided many new applications which are described in the following. We have the honour to present here the proceedings of this Symposium. st th The Symposium took place from august 31 to September 4 at the Institut International de la Prospective in Futuroscope near Poitiers. A significant number of internationally renowned specialists had expressed their wish to participate in this meeting. The Scientific Committee proposed 16 general conferences and selected 33 regular lectures and 17 poster presentations. Papers corresponding to posters are not differentiated in the proceedings from those that were presented orally. It is worth noting that a total of 80 participants, representing 16 countries, registered for this symposium.. The Scientific Committee deserves praise for attracting a significant number of young scientists, both as authors and as participants. Let us add our warm acknowledgements to Professor J.W. Dally and to Professor A.S. Kobayashi who, throughout the symposium preparation time, brought us valuable help.
