The subject of geomaterial interfaces recognizes the important influences of the interface behaviour on the performance of interfaces involving cementaceous materials such as concrete and steel, ice-structure interfaces, concrete-rock interfaces and interfaces encountered in soil reinforcement. During the past two decades, the subject of geomaterial interfaces has attracted the concerted attention of scientists and engineers both in geomechanics and applied mechanics. These efforts have been largely due to the observation that the conventional idealizations of the behaviour of interfaces between materials by frictionless contact, bonded contact, Coulomb friction or finite friction tend to omit many interesting and important influences of special relevance to geomaterials. The significant manner in which non-linear effects, dilatancy, contact degradation, hardening and softening, etc., can influence the behaviour of the interface is borne out by experimental evidence. As a result, in many instances, the response of the interface can be the governing criterion in the performance of a geomechanics problem. The primary objective of this volume is to provide a documentation of recent advances in the area of geomaterial interfaces. The volume consists of subject groupings which cover ice-structure, soil-structure and steel-concrete interfaces, mechanics of rock and concrete joints and interfaces in discrete systems.

The disturbed state concept (DSC) is a unified, constitutive modelling approach for engineering materials that allows for elastic, plastic, and creep strains, microcracking and fracturing, stiffening or healing, all within a single, hierarchical framework. Its capabilities go well beyond other available material models yet lead to significant simpl

This book presents a complete and comprehensive analysis of the behaviour of granular materials including the description of experimental results, the different ways to define the global behaviour from local phenomena at the particle scale, the various modellings which can be used for a D.E.M. analysis to solve practical problems and finally the analysis of strain localisation. The concepts developed in this book are applicable to many kinds of granular materials considered in civil, mechanical or chemical engineering.

This conference brought together specialists in cyclic soil behaviour in order to discuss important results and new ideas in the field, and to share expertise in design of various problems involving cyclic or dynamic behaviour of soils. This book covers a variety of topics: * Theory and analysis, including constitutive relations of soil under cyclic loading, post-seismic stability analysis of soil/structure, dynamic stability of structures, liquefaction analysis of marine structures due to cyclic loading, and more * Cyclic and dynamic laboratory and model testing, centrifuge testing and in-situ testing. * Numerical analysis, including computer methods * Design of industrial applications and marine structures, installation methods of piles, vibrocompaction, densification of ballast in railway structures, case studies of earthquakes and post-liquefaction observations.

This book presents a state-of-the-art exposition of the broad subject of the mechanics of geomaterials, from rocks and soils to concrete and reinforced concrete. Its approach is interdisciplinary, with an emphasis placed on the fundamental problems of mechanics which are common to structural and civil engineering, geotechnical and mining engineering, nuclear engineering, offshore engineering and geology. The consideration of these problems emphasises the importance of experimental observation, and concentrates on the use of numerical methods, particularly the finite element method, for their solution.
