Bésuelle and published by . This book was released on 2016 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new experimental apparatus for rock-specimen analysis has been developed in Laboratoire 3SR (Grenoble) to characterize the evolution under loading of the deformation mode, placing particular attention on the onset of strain localization and the post-localization regime in rocks. The experimental apparatus can be configured to apply true triaxial or plane strain conditions on prismatic specimens, with a confining pressure of up to 100 MPa. The three principal stresses are independently controlled to apply true triaxial conditions. When applying plane strain conditions, the stress perpendicular to the observed specimen's surface is proportionally varied as a function of the loading applied on the specimen, to satisfy the condition of zero strain along this direction. The prismatic specimen can be observed under loading, because its surface, orthogonal with the direction of the intermediate principal stress, is in contact with a hard window (sapphire), thus allowing pictures to be taken throughout the test, as well as enabling full-field measurement. Photographs are analyzed by digital image correlation (DIC) to measure displacement and strain fields. The new true triaxial apparatus is presented here, first with a description of the experimental setup and mechanical characteristics of the cell. Then, the experimental procedure adopted to apply and assess the speckle pattern on the sample's surface, as required for DIC, is detailed. Finally, selected results from a test performed with the true triaxial device on a Vosges sandstone sample, performed in plane strain compression, are shown. The onset of strain localization and the shear bands' pattern evolution are shown by means of incremental strain fields obtained by DIC.
Book Synopsis Instabilities Modeling in Geomechanics by : Ioannis Stefanou
Download or read book Instabilities Modeling in Geomechanics written by Ioannis Stefanou and published by John Wiley & Sons. This book was released on 2021-03-12 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Instabilities Modeling in Geomechanics describes complex mechanisms which are frequently met in earthquake nucleation, geothermal energy production, nuclear waste disposal and CO2 sequestration. These mechanisms involve systems of non-linear differential equations that express the evolution of the geosystem (e.g. strain localization, temperature runaway, pore pressure build-up, etc.) at different length and time scales. In order to study the evolution of a system and possible instabilities, it is essential to know the mathematical properties of the governing equations. Therefore, questions of the existence, uniqueness and stability of solutions naturally arise. This book particularly explores bifurcation theory and stability analysis, which are robust and rigorous mathematical tools that allow us to study the behavior of complex geosystems, without even explicitly solving the governing equations. The contents are organized into 10 chapters which illustrate the application of these methods in various fields of geomechanics.

Download or read book Applications of X-ray Computed Tomography in the Geosciences written by Florias Mees and published by Geological Society of London. This book was released on 2003 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray computed tomography (CT) is a technique that allows non-destructive imaging and quantification of internal features of objects. X-ray CT reveals differences in density and atomic composition and can therefore be used for the study of porosity, the relative distribution of contrasting solid phases and the penetration of injected solutions. In this book, various applications of X-ray CT in the geosciences are illustrated by papers covering a wide range of disciplines, including petrology, soil science, petroleum geology, geomechanics and sedimentology.

Download or read book Unified Strength Theory and Its Applications written by Mao-Hong Yu and published by Springer Science & Business Media. This book was released on 2004-01-08 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been ten years since I presented the paper entitled “A new model and theory on yield and failure of materials under the complex stress state” at the Sixth Conference on Mechanical Behaviour of Materials held at Kyoto, Japan in 1991. The proceedings edited by Jono and Inoue were published by Pergamon Press in 1991. At that conference Professor Murakami and I were invited to act as the chairperson and co-chairperson of a session, and I presented the paper at another session. Few days before the conference, I had given a seminar regarding the tw- shear strength theory and the unified strength theory at Nagoya Technological University. These were the first two presentations of the unified strength theory, although I had completed the research of the unified strength theory in 1990. The paper “Twin-shear strength theory and its generalization” was published in the English edition of Sciences in China, the top journal in China, in 1985. The th original generalized twin-shear strength theory was presented at the 16 International Theoretical and Applied Mechanics Congress held at Copenhagen in Denmark and MPA (MaterialPrüfungsAnstalt) at Stuttgart University, Germany in 1984. After this Congress I visited the MPA and School of Civil Engineering of Stuttgart University, and gave a seminar regarding the generalized twin-shear strength theory at MPA of Stuttgart University. Professor Otto Mohr (1835–1918) has had worked at the Stuttgart University. He was a very good professor, his lectures aroused great interest in his students.

Download or read book Advanced Triaxial Testing of Soil and Rock written by Robert T. Donaghe and published by ASTM International. This book was released on 1988 with total page 896 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Although the triaxial compression test is presently the most widely used procedure for determining strength and stress-deformation properties of soils, there have been no books published on triaxial testing since the 1962 second edition of the landmark work The Measurement of Soil Properties in the Triaxial Test by Bishop and Henkel. It is apparent there is a need to document advances made in triaxial testing since publication of Bishop and Henkel's book and to examine the current state of the art in a forum devoted solely to triaxial testing. Because of increasing versatility brought about by recent developments in testing techniques and equipment, it is also important that the geotechnical profession be provided with an up-to-date awareness of potential uses for the triaxial test."--Overview.

Book Synopsis Experimental Rock Deformation - The Brittle Field by : M. S. Paterson
Download or read book Experimental Rock Deformation - The Brittle Field written by M. S. Paterson and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph deals with the part of the field of ex-' perimental rock deformation that is dominated by the phenomena of brittle fracture on one scale or another. Thus a distinction has been drawn between the fields of brittle und ductile behaviour in rock, corresponding more or less to a distinction between the phenomena of fracture and flow. It is hoped eventually to present a survey of the ductile field in a separate volume. The last chapter of this volume deals with the transition between the two fields. The scope of this survey has been limited to the mec.hanical properties of rock viewed as a material on the laboratory scale. Thus, the topic and approach is of a "materials science" kind rather than of a "structures" kind. We are dealing with only one part of the wider field of rock mechanics, which also includes structural or boundary value problems, for example, those of the stability of slopes, the collapse of mine openings, earth quakes, the folding of stratified rock, and the convec tive motion of the earth's mantle. One topic thus ex cluded is the role of jointing, which it is commonly necessary to take into account in applications in engi neering and mining, and probably often in geology too.
