Soils are composed of grains but they are generally treated as continua in the classical framework of geomechanics. Their macroscopic response under loading, such as their non-linearity, yielding and anisotropy, is controlled by their micro-structure, the characteristics of the grains and the disposition of contacts between them. There have been rapid advances in technology both to investigate the microscopic properties of soils, and to simulate their granular behaviour explicitly through Discrete Element Method (DEM). DEM was originally used to reproduce element tests, but it is now being advocated for boundary-value problems. Geomechanics and Geotechnics: From Micro to Macro includes 174 peer-reviewed papers presented at the International Symposium on Geomechanics and Geotechnics: From Micro to Macro (IS-Shanghai 2010, Shanghai, China, 10-12 October 2010). The symposium provided an opportunity for the exchange of ideas and information on experiments, numerical models and engineering applications related to the discrete nature of geomaterials. The main goal was to explore further advances in the use of micro-geomechanical approaches, and by doing so to improve the understanding of macro-geomechanical phenomena by offering experiments, constitutive relations, numerical analyses and engineering applications associated with the discrete nature of geomaterials. Geomechanics and Geotechnics: From Micro to Macro will be of interest to academics and engineers involved in Soil Mechanics, Geomechanics, Geotechnical Engineering, Geoengineering and Civil Engineering.

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.

Modeling in Geomechanics Edited by Musharraf Zaman The University of Oklahoma, USA Giancarlo Gioda Politecnico di Milano, Italy John Booker University of Sydney, Australia Geomechanics is an interdisciplinary field involving the study of natural and man-made systems with emphasis on the mechanics of various interacting phenomena. It comprises numerous aspects of engineering and scientific disciplines, which share common bases in mathematics, mechanics and physics. In recent years, with the extraordinary growth of computing power and resources, progress in the generation of new theories and techniques for the analysis of geomechanics problems has far surpassed their actual use by practitioners. This has led to a gap between our ability to deal with complex, inter-disciplinary problems in geomechanics and the actual impact of these advances on engineering practice. This book contains contributions from an international group of accomplished researchers and practitioners from various branches of soil and rock engineering, and presents the latest theoretical developments and practical applications of modeling in geomechanics. Chapters are grouped into four main sections: * Computational procedures * Constitutive modeling and testing * Modeling and simulation * Applications Efforts have been made to include recent developments and provide suggestions and examples as to how these can be applied in modeling actual engineering problems. Researchers, practitioners and students in geomechanics, mechanics of solids, soil and rock engineering will find this book an invaluable reference.

Theories of surface waves develop since the end of XIX century and many fundamental problems like existence, phase and group velocities, attenuation (quality factor), mode conversion, etc. have been, in part successfully, solved within the framework of such simple models as ideal fluids^ or linear elasticity. However, a sufficiently complete presentation of this subject, particularly for solids, is still missing in the literature. The sole exception is the book of I. A. Viktorov^ which contains an extensive discussion of fundamental properties of surface waves in homogeneous and stratified linear elastic solids with particular emphasis on contributions of Russian scientists. Unfortunately, the book has never been translated to English and its Russian version is also hardly available. Practical applications of surface waves develop intensively since a much shorter period of time than theories even though the motivation of discoverers of surface waves such as Lord Rayleigh stems from their appearance in geophysics and seismology. Nowadays the growing interest in practical applications of surface waves stem from the following two main factors: surface waves are ideal for developing relatively cheap and convenient methods of nondestructive testing of various systems spanning from nanomaterials (e.g.

Environmental Geomechanics cover a wide range of topics concerned with the mechanical behaviour of geomaterials. The problems addressed are complex, mainly due to the coexistence of several species and phases, to their interaction and their often non-linear behaviour. Experimental evidence is difficult to obtain and laboratory as well as in-situ testing procedures present serious challenges. Numerical techniques are used to solve the complex non-linear analytical systems. Integration of new models for engineering applications will require a considerable effort among engineering teams. Due to the number of phenomena influencing the solutions an interdisciplinary approach to Environmental Geomechanics is therefore necessary. The first part of the volume contains invited keynote lectures addressing various aspects of the subject of Environmental Geomechanics. It can serve as a starting point for further research thanks to its in-depth treatment and its rich bibliographic references. The second part contains various selected contributions. These reflect the broad scope of Environmental Geomechanics and appeal for more research efforts in this domain. Many practical problems relating to engineering practice are also presented which make the book an invaluable "state of the art" guide in this very important field.
