Available in PDF, EPUB and Kindle. Book excerpt: Microscopic re-examination of geomaterials consisting of aggregates can shed light on macroscopic behaviour, including compressibility, anisotropy, yielding, creep, cyclic liquefaction and shear rupture. As a result of this process of examination, new methods of material characterization emerge, leading to a greater degree of accuracy in the specification of new constitutive models with physically-meaningful parameters. The impetus behind this development is an increasing awareness on sustainability, leading to the more efficient use of recycled materials for geotechnical applications. The characteristics of recycled materials, such as compressibility and self-hardening, may differ significantly from those of natural materials, and it is crucial that evaluation is made from a specifically particulate perspective.

Available in PDF, EPUB and Kindle. Book excerpt: Although rigidity has been studied since the time of Lagrange (1788) and Maxwell (1864), it is only in the last twenty-five years that it has begun to find applications in the basic sciences. The modern era starts with Laman (1970), who made the subject rigorous in two dimensions, followed by the development of computer algorithms that can test over a million sites in seconds and find the rigid regions, and the associated pivots, leading to many applications. This workshop was organized to bring together leading researchers studying the underlying theory, and to explore the various areas of science where applications of these ideas are being implemented.

Download or read book Numerical Modelling of Construction Processes in Geotechnical Engineering for Urban Environment written by Theodoros Triantafyllidis and published by CRC Press. This book was released on 2006-02-23 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has become increasingly important, particularly in an urban environment, to predict soil behaviour and to confine the settlement or deformation of buildings adjacent to construction sites. One important factor is the choice of construction procedure for the installation of piles, sheet pile walls, anchors or for soil improvement techniques, ground freezing and tunnelling methods. The modelling of construction processes, which are frequently associated with large deformations of the soil and with strong changes in the structure of the soil around the construction plant, in the case of, for example, a drill, a bit, a vibrator, or an excavation tool, requires sophisticated and new methods in numerical modelling. Often the simulation of the construction procedure is neglected in the calculations. Such methods are described and discussed in this book, as are examples of the methods applied to geotechnical practice, field and laboratory testing as well as case studies. This volume provides a valuable source of reference for scientists in geotechnical engineering and numerical modelling, geotechnical engineers, post graduate students, construction companies and consultants, manufacturers of geotechnical construction plants and software suppliers and developers of geotechnical construction methods.

Available in PDF, EPUB and Kindle. Book excerpt: Solutions for soil engineering and soil-structure interaction problems need realistic and pertinent experimental and modelling tools. In this work, extensive developments proposed by the invited speakers of the Lyon International Symposium held in September 2003 are presented, including experimental investigations into deformation properties; laboratory, in-situ and field observation interpretations; behaviour characterisation and modelling; and case histories. The contributions include recent investigations into anisotropy and non-linearity, the effects of stress-strain-time history, ageing and time effects, yielding, failure and flow, cyclic and dynamic behaviour. In addition, advanced geotechnical testing is applied to real engineering problems, and to ways of synthesising information from a range of sources while engaging in practical site characterisation studies.

Download or read book Modelling of Soil Behaviour with Hypoplasticity written by David Mašín and published by Springer. This book was released on 2018-12-12 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains the hypoplastic modelling framework. It is divided into two parts, the first of which is devoted to principles of hypoplasticity. First, the basic features of soil’s mechanical behaviour are introduced, namely non-linearity and asymptotic properties. These features are then incorporated into simple one-dimensional hypoplastic equations for compression and shear. Subsequently, a hypoplastic equivalent of the Modified Cam-Clay model is developed in 2D space using stress and strain invariants to demonstrate key similarities and differences between elasto-plastic and hypoplastic formulations. Lastly, the mathematical structure of hypoplastic models is explained by tracing their historical development, from the early trial-and-error models to more recent approaches. In turn, Part II introduces specific hypoplastic models for soils. First, two reference models for sand and clay are defined. After summarising their mathematical formulations, calibration procedures are described and discussed. Subsequently, more advanced modelling approaches are covered: the intergranular strain concept incorporating the effects of small strain stiffness and cyclic loading, viscohypoplasticity for predicting rate effects, soil structure to represent structured and bonded materials and soil anisotropy. The book concludes with a description of partial saturation and thermal effects: topics that are increasingly important to the disciplines of energy and environmental geotechnics. Selecting a constitutive model and its parameters is often the most important and yet challenging part of any numerical analysis in geotechnical engineering. Hypoplasticity involves a specific class of soil constitutive models, which are described in detail here. The book offers an essential resource, both for model users who need a more advanced model for their geotechnical calculations and are mainly interested in parameter calibration procedures, and for model developers who are seeking a comprehensive understanding of the mathematical structure of hypoplasticity.

Download or read book Characterization and Behavior of Interfaces written by J. David Frost and published by IOS Press. This book was released on 2010 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interfaces exist in every geotechnical system in many forms and at multiple scales. Although historically, they are often considered to be the weak link in a system, particularly as the result of a number of unexpected catastrophic failures, new insight gained over the past twenty years by researchers around the world has shown that it is possible to select combinations of materials and design an engineered interface so that it is at least as strong as the surrounding materials. These new insights have been gained as a result of experimental study, numerical modeling and analytical investigation of successful and failed systems. While individual technical papers have been presented and/or published in various forums and proceedings over the years, no technical event has ever been convened for the sole purpose of allowing for exchange of information and ideas pertaining to geotechnical interfaces. The research symposium held in September 2008 in Atlanta Georgia, USA, in conjunction with the Fourth International Symposium on Deformation Characteristics of Geomaterials (IS Atlanta 2008) at the Georgia Institute of Technology on The Characterization and Behavior of Interfaces addressed this deficiency and the papers presented at that event are contained in this publication.

Download or read book Shear Behavior of Composite Soils written by Yanrong Li and published by CRC Press. This book was released on 2016-12-08 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has the purpose of developing an understanding of the factors determining and influencing the shear behavior of soils, with emphasis on composite soils, as they are the most encountered materials in geological and geotechnical engineering in mountainous areas. This objective is reached by examining the soil compressibility, structure of shear zone and its evolution, and water content of shear zone and shear mode of soils together with analyses of the influences of intrinsic properties, e.g. Atterberg limits, particle size distribution, particle shape, and testing conditions, e.g. normal stress and shearing rate. An in-depth review is presented in an approximately chronological order and covers almost all the factors that are believed to influence the mechanical behavior of soils. The equipment and test techniques for shear strength of soils are detailed. The residual shear behavior of composite soil is investigated by means of a systematic laboratory testing program using a large ring shear apparatus and an intermediate direct shear box. The Fast Fourier Transform is employed for the first time to analyze the fluctuations of measured shearstress and discovers the close relationships with both intrinsic properties of soils and testing conditions. Although the book is aimed primarily at researchers in geological and geotechnical engineering, it contains material of interest to students of geology and soil science and also should be a useful reference for practicing engineers faced with composite soils.
