Book Synopsis Torsional Shear Testing Technique for Dynamic Properties of Clay by : AG. Franklin
Download or read book Torsional Shear Testing Technique for Dynamic Properties of Clay written by AG. Franklin and published by . This book was released on 1969 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The testing technique and apparatus described herein implement the determination of dynamic stress-strain-time properties of clay soils over several decades of the frequency spectrum, including the normal frequency range of most earthquakes. The basic device used for these tests is the Weissenberg rheogoniometer, with some modifications to enhance its adaptability to testing soils. The soft clay test specimens are held in a cone-and-plate sample holder, while a hollow cylinder geometry is more suitable for stiff clay specimens. These geometries satisfy reasonably well the desirable condition that stresses and strains be homogeneous within the test specimen, and they allow tests to be conducted over a wide range of moisture contents. The specimens are subjected to oscillatory torsional shear deformations, and the moment response is measured; with the use of the specimen geometry and the homogeneity of stress and strain, these deformations and forces are readily converted to shear stresses and shear strains. In addition to the magnitudes of stress and strain, the time difference between corresponding points on the stress and strain curves is measured, allowing computation of a phase angle between stress and strain. Two types of oscillatory tests are particularly convenient to perform in this apparatus; in one case, the frequency is maintained constant while the deformation amplitude is varied, while in the other case, deformation amplitude is held constant and frequency is varied. Data obtained by this technique allow the evaluation of several aspects of the dynamic clay behavior, such as the effect of stress history, the degree of nonlinearity in the stress-strain response, and the extent to which presently available theories, such as linear viscoelasticity, can be used to interpret the mechanical behavior. For example, the energy dissipated in a unit volume of the sample over a single cycle of deformation can be calculated by using the phase angle and the stress and strain amplitudes; alternatively, this dissipated energy can be measured directly by means of a hysteresis loop, and the two values can be compared.
Book Synopsis Feasibility of a Tool for In Situ Measurement of Material Properties of Clays Over a Wide Strain Range by : CK. Chan
Download or read book Feasibility of a Tool for In Situ Measurement of Material Properties of Clays Over a Wide Strain Range written by CK. Chan and published by . This book was released on 1994 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Initial feasibility findings of a research program directed toward the development of a practical tool for rapid in situ determination of material properties (modulus and damping) of soft to medium-stiff clays over a wide range of strain (0.0001% to 10%) are presented. The motivation for this work is discussed in terms of both the sensitivity of earthquake ground response analyses to input material properties, as well as the limitations of existing design methodologies for specifying material behavior. The scope and objectives of the research program are outlined. Results are presented from numerical analyses used to establish typical stress and strain fields caused by borehole installation. The merits of several tool-design alternatives are considered, and preliminary design concepts for a new tool called the "Freestanding Torsional Shear (FTS)" device are introduced. Critical issues and future directions of the research program are discussed.

Book Synopsis Handbook of Geotechnical Investigation and Design Tables by : Burt G. Look
Download or read book Handbook of Geotechnical Investigation and Design Tables written by Burt G. Look and published by CRC Press. This book was released on 2007-04-26 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical handbook of properties for soils and rock contains, in a concise tabular format, the key issues relevant to geotechnical investigations, assessments and designs in common practice. In addition, there are brief notes on the application of the tables. These data tables are compiled for experienced geotechnical professionals who require a reference document to access key information. There is an extensive database of correlations for different applications. The book should provide a useful bridge between soil and rock mechanics theory and its application to practical engineering solutions. The initial chapters deal with the planning of the geotechnical investigation, the classification of the soil and rock properties and some of the more used testing is then covered. Later chapters show the reliability and correlations that are used to convert that data in the interpretative and assessment phase of the project. The final chapters apply some of these concepts to geotechnical design. This book is intended primarily for practicing geotechnical engineers working in investigation, assessment and design, but should provide a useful supplement for postgraduate courses.

This book was released on 2006-01-31 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of geoengineering is at a crossroads where the path to high-tech solutions meets the path to expanding applications of geotechnology. In this report, the term "geoengineering" includes all types of engineering that deal with Earth materials, such as geotechnical engineering, geological engineering, hydrological engineering, and Earth-related parts of petroleum engineering and mining engineering. The rapid expansion of nanotechnology, biotechnology, and information technology begs the question of how these new approaches might come to play in developing better solutions for geotechnological problems. This report presents a vision for the future of geotechnology aimed at National Science Foundation (NSF) program managers, the geological and geotechnical engineering community as a whole, and other interested parties, including Congress, federal and state agencies, industry, academia, and other stakeholders in geoengineering research. Some of the ideas may be close to reality whereas others may turn out to be elusive, but they all present possibilities to strive for and potential goals for the future. Geoengineers are poised to expand their roles and lead in finding solutions for modern Earth systems problems, such as global change, emissions-free energy supply, global water supply, and urban systems.
Book Synopsis Developments in Dynamic Soil-Structure Interaction by : Polat Gülkan
Download or read book Developments in Dynamic Soil-Structure Interaction written by Polat Gülkan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the last couple of decades it has been recognized that the foundation material on which a structure is constructed may interact dynamically with the structure during its response to dynamic excitation to the extent that the stresses and deflections in the system are modified from the values that would have been developed if it had been on a rigid foundation. This phenomenon is examined in detail in the book. The basic solutions are examined in time and frequency domains and finite element and boundary element solutions compared. Experimental investigations aimed at correlation and verification with theory are described in detail. A wide variety of SSI problems may be formulated and solved approximately using simplified models in lieu of rigorous procedures; the book gives a good overview of these methods. A feature which often lacks in other texts on the subject is the way in which dynamic behavior of soil can be modeled. Two contributors have addressed this problem from the computational and physical characterization viewpoints. The book illustrates practical areas with the analysis of tunnel linings and stiffness and damping of pile groups. Finally, design code provisions and derivation of design input motions complete this thorough overview of SSI in conventional engineering practice. Taken in its entirety the book, authored by fifteen well known experts, gives an in-depth review of soil-structure interaction across a broad spectrum of aspects usually not covered in a single volume. It should be a readily useable reference for the research worker as well as the advance level practitioner. (abstract) This book treats the dynamic soil-structure interaction phenomenon across a broad spectrum of aspects ranging from basic theory, simplified and rigorous solution techniques and their comparisons as well as successes in predicting experimentally recorded measurements. Dynamic soil behavior and practical problems are given thorough coverage. It is intended to serve both as a readily understandable reference work for the researcher and the advanced-level practitioner.
Book Synopsis Clay-Polymer Nanocomposites by : Khouloud Jlassi
Download or read book Clay-Polymer Nanocomposites written by Khouloud Jlassi and published by Elsevier. This book was released on 2017-07-26 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clay–Polymer Nanocomposites is a complete summary of the existing knowledge on this topic, from the basic concepts of synthesis and design to their applications in timely topics such as high-performance composites, environment, and energy issues. This book covers many aspects of synthesis such as in- situ polymerization within the interlamellar spacing of the clays or by reaction of pristine or pre-modified clays with reactive polymers and prepolymers. Indeed, nanocomposites can be prepared at industrial scale by melt mixing. Regardless the synthesis method, much is said in this book about the importance of theclay pre-modification step, which is demonstrated to be effective, on many occasions, in obtaining exfoliated nanocomposites. Clay–Polymer Nanocomposites reports the background to numerous characterization methods including solid state NMR, neutron scattering, diffraction and vibrational techniques as well as surface analytical methods, namely XPS, inverse gas chromatography and nitrogen adsorption to probe surface composition, wetting and textural/structural properties. Although not described in dedicated chapters, numerous X-ray diffraction patterns of clay–polymer nanocomposites and reference materials are displayed to account for the effects of intercalation and exfoliations of layered aluminosilicates. Finally, multiscale molecular simulation protocols are presenting for predicting morphologies and properties of nanostructured polymer systems with industrial relevance. As far as applications are concerned, Clay–Polymer Nanocomposites examines structural composites such as clay–epoxy and clay–biopolymers, the use of clay–polymer nanocomposites as reactive nanocomposite fillers, catalytic clay-(conductive) polymers and similar nanocomposites for the uptake of hazardous compounds or for controlled drug release, antibacterial applications, energy storage, and more. The most comprehensive coverage of the state of the art in clay–polymer nanocomposites, from synthesis and design to opportunities and applications Covers the various methods of characterization of clay–polymer nanocomposites - including spectroscopy, thermal analyses, and X-ray diffraction Includes a discussion of a range of application areas, including biomedicine, energy storage, biofouling resistance, and more
