Download or read book Photoelasticity written by M. M. Leven and published by Elsevier. This book was released on 2013-10-22 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photoelasticity presents the development of photoelasticity. This book discusses the principle of optical equivalence of stressed isotropic bodies. Organized into 29 chapters, this book begins with an overview of the progress in three-dimensional photoelasticity. This text then summarizes the approximate theoretical analysis by the strain-energy technique and derives the basic equations for the evaluation of P and Q by graphical integration. Other chapters consider the importance of stress concentrations in the domain of strength of materials, particularly where fatigue is present. This book discusses a well the various instructive fractures and indicates that the strength of bakelite is determined by the maximum tensile stresses as computed by advanced methods of stress analysis. The final chapter deals with the two fundamental problems in three-dimensional photoplasticity and explains the general stress-optic law under plastic flow without unloading. This book is a valuable resource for designers as well as mechanical and civil engineers.

Available in PDF, EPUB and Kindle. Book excerpt: Photoelasticity as an experimental method for analyzing stress fields in mechanics was developed in the early thirties by the pioneering works of Mesnager in France and Coker and Filon in England. Almost concurrently, Föppl, Mesmer, and Oppel in Germany contributed significantly to what turned out to be an amazing development. Indeed, in the fifties and sixties a tremendous number of scientific papers and monographs appeared, all over the world, dealing with various aspects of the method and its applications in experimental stress analysis. All of these contributions were based on the so-called Neumann-Maxwell stress-opticallaw; they were developed by means of the classical methods of vector analysis and analytic geometry, using the conventionallight-vector concept. This way of treating problems of mechanics by photoelasticity indicated many shortcomings and drawbacks of this classical method, especially when three-dimensional problems of elasticity had to be treated and when complicated load and geometry situations existed. Meanwhile, the idea of using the Poincare sphere for representing any polarization profile in photoelastic applications was introduced by Robert in France and Aben in the USSR, in order to deal with problems of polarization oflight passing through aseries of optical elements (retarders andjor rotators). Although the Poincare-sphere presentation of any polarization profile con stitutes a powerful and elegant method, it exhibits the difficulty of requiring manipulations in three-dimensional space, on the surface of the unit sphere. However, other graphical methods have been developed to bypass this difficulty.

Book excerpt: Physical models have been, and continue to be used by engineers when faced with unprecedented challenges, when engineering science has been non-existent or inadequate, and in any other situation when the engineer has needed to raise their confidence in a design proposal to a sufficient level to begin construction. For this reason, models have mostly been used by designers and constructors of highly innovative projects, when previous experience has not been available. The book covers the history of using of physical models in the design and development of civil and building engineering projects including bridges in the mid-18th century, William Fairbairn?s Britannia bridge in the 1840s, the masonry Aswan Dam in the 1890s, concrete dams in the 1920s, thin concrete shell roofs and the dynamic behaviour of tall buildings in earthquakes from the 1930s, tidal flow in estuaries and the acoustics of concert halls from the 1950s, and cable-net and membrane structures in the 1960s. Traditionally, progress in engineering has been attributed to the creation and use of engineering science, the understanding materials properties and the development of new construction methods. The book argues that the use of reduced scale models have played an equally important part in the development of civil and building engineering. However, like the history of engineering design itself, this crucial contribution has not been widely reported or celebrated. The book concludes with reviews of the current use of physical models alongside computer models, for example, in boundary layer wind tunnels, room acoustics, seismic engineering, hydrology, and air flow in buildings.
Download or read book Photoelasticity of Glass written by Hillar Aben and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glass is the oldest man-made material. Its invention about five thousand years ago should be considered as one of the crucial events in the history of mankind. Glass has given man the possibility to have daylight in his protected living environment and to compensate the defects of his sight. Glass containers and tableware have played and still play an important role in man's everyday life. Glass elements in microscopes and telescopes have given us the possibility to learn the secrets of micro- and macrocosm. Glass participates in the most sophisticated technologies: glass fibers have caused a revolution in telecommunication, glass is used as a material for many modern electronic devices. Although nowadays plastics often make a strong competition to glass, for many applications glass is still the best material due to its specific properties - its hardness, good transparency, resistance to chemicals, the easiness to shape glass articles, feasibility to change the composition of the glass in order to meet new specific demands, etc. Two peculiarities of glass should be pointed out. The first is the fragility of glass - it breaks easily due to tensile stresses. The second is the fact that in every glass item there exist residual stresses due to the complicated technological process during which glass from the state of a viscous liquid at high temperature turns into solid state, while cooled down.

This book was released on 2012-12-06 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive treatise reviews, for the first time, all the essential work over the past 160 years on the photoelastic and the closely related linear and quadratic electro-optic effects in isotropic and crystalline mate rials. Emphasis is placed on the phenomenal growth of the subject during the past decade and a half with the advent of the laser, with the use of high-frequency acousto-optic and electro-optic techniques, and with the discovery of new piezoelectric materials, all of which have offered a feedback to the wide interest in these two areas of solid-state physics. The first of these subjects, the photoelastic effect, was discovered by Sir David Brewster in 1815. He first found the effect in gels and subsequently found it in glasses and crystals. While the effect remained of academic interest for nearly a hundred years, it became of practical value when Coker and Filon applied it to measuring stresses in machine parts. With one photograph and subsequent analysis, the stress in any planar model can be determined. By taking sections of a three-dimensional model, complete three-dimensional stresses can be found. Hence this effect is widely applied in industry.

Download or read book Experimental Stress Analysis written by H. Wieringa and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Designing and manufacturing structures of all kinds in an economic and a safe way is not possible without doing experimental stress analysis. The modernity of structures, with their higher reliability demands, as well as today's more stringent safety rules and extreme environmental conditions necessitate the improvement of the measuring technique and the introduction of new ones. Although theoretical/mathematical analysis is improving enormously, an example of which is the finite element model, it cannot replace experimental analysis and vice versa. Moreover, the mathematical analysis needs more and more accurate parameter data which in turn need improved experimental investigations. No one can do all those investigations on his own. Exchange of knowledge and experience in experimental stress analysis is a necessity, a thing acknowledged by every research worker. Therefore, the objective of the Permanent Committee for Stress Analysis (PC SA) is to promote the organization of conferences with the purpose disseminating new research and new measuring techniques as well as improvements in existing techniques, and furthermore, to promote the exchange of experiences of practical applications with techniques. rhis Vlllth International Conference on Experimental Stress Analysis on behalf of the PC SA is one in a series which started in 1959 at Delft (NL), and was followed by conferences at Paris (F), Berlin-W, Cambridge (~K), Udine (I), Munich (FRG) and Haifa (Isr.). Such a Conference will be held in Europe every fourth year, half-way bewteen the IUTAM Congresses.
