This practical guide provides the best introduction to large deformation material point method (MPM) simulations for geotechnical engineering. It provides the basic theory, discusses the different numerical features used in large deformation simulations, and presents a number of applications -- providing references, examples and guidance when using MPM for practical applications.MPM covers problems in static and dynamic situations within a common framework. It also opens new frontiers in geotechnical modelling and numerical analysis. It represents a powerful tool for exploring large deformation behaviours of soils, structures and fluids, and their interactions, such as internal and external erosion, and post-liquefaction analysis; for instance the post-failure liquid-like behaviours of landslides, penetration problems such as CPT and pile installation, and scouring problems related to underwater pipelines. In the recent years, MPM has developed enough for its practical use in industry, apart from the increasing interest in the academic world.

The improved, new edition of the classic book on the physical properties of soilFundamentals of Soil Behavior, Third Edition is the thoroughly updated, expanded, and revised edition of this highly distinguished publication in geotechnical engineering. Filled with useful tables and graphs illustrating correlations among composition, classification, state, and static and dynamic properties, this Third Edition continues the tradition of providing the latest information on the physical properties of soil and the fundamentals of its behavior over time.Students and busy professionals will connect with this new edition's timesaving, streamlined format and its greater emphasis on practical exercise problems involving advanced concepts of soil behavior. Other must-read features of this Third Edition include: New, expanded material on micro-mechanical behavior at the particulate level and its influences on engineering properties at the macro-scaleA new chapter on time effects on soil deformation at different stress and strain levelsNew coverage of such important topics as environmental geotechnics, biological influences on soil behavior, soil fracturing, the effects of time, and geochemical problemsSets of questions and problems at the end of each chapter, a feature not available in prior editionsFundamentals of Soil Behavior, Third Edition is an essential text for graduate students and researchers as well as a peerless reference for geotechnical, environmental, and civil engineers and geologists.

Wireless Sensor Networks for Civil Infrastructure Monitoring provides expert guidance on the selection and use of wireless sensor network (WSN) technology for structural monitoring of both existing infrastructure and new construction projects. The purpose of this guide is to consolidate a generic methodology for the design and implementation of WSNs for monitoring civil engineering infrastructure, coupled with best practice for data management and information valuation.Wireless Sensor Networks for Civil Infrastructure Monitoring:aims to address a wide range of monitoring objectives, including monitoring undertaken in support of construction work, in response to specific problems identified during inspections, long-term monitoring over the whole life of an asset and for research purposesintends to assist stakeholders in the identification of the key performance criteria for a monitoring systemincludes highly illustrated real-world case studiescontains a detailed reference list for further reading on specific topics.Part of a series of best practice guides written by experts at the Cambridge Centre for Smart Infrastructure and Construction (CSIC), this book provides valuable information which will be useful to a range of stakeholders involved in the management of infrastructure assets.

Authoritative and generously illustrated resource covering the many properties of soil and its behavior needed for addressing geotechnical and geoenvironmental engineering projects and problems. The Fourth Edition of Fundamentals of Soil Behavior has been thoroughly updated to provide the latest information on the physical properties of soil and the fundamentals of its behavior, with hundreds of tables and graphs illustrating correlations among composition, classification, state, and static and dynamic properties. Overall, each topic is addressed in a micro-to-macro sequence, considering behaviors at the atomic and/or particle scales to develop understanding of soil properties and behaviors at the macro-scale, which is relevant to engineering practice. This Fourth Edition includes two new chapters on special features of soil behavior and temperature-dependent soil behavior. Other chapters have been substantially updated to include the latest developments in imaging technology, and analysis numerical simulations that have advanced research on the complexities of soil behavior, and recent experimental data. The content has been reviewed, consolidated, and reorganized to more effectively comunicate key information. The text features end-of-chapter questions and problems to aid in seamless reader comprehension and information retention. Updated by true thought leaders in the field, the Fourth Edition of Fundamentals of Soil Behavior includes detailed information on: Soil formation, covering the earth’s crust, the geologic cycle, rock and mineral stability, weathering, and origin of clay minerals and genesis.Soil mineralogy, covering atomic structure, interatomic bonding, secondary bonds, crystal notation, and clay mineral characteristics.Fundamental engineering characterization of soil, covering granular soils and clay minerals.Observing and quantifying soil fabric, covering qualitative and quantitative assessment of soil fabric.Transport of heat, fluid, and electrical current.The fundamentals of volume change, deformation, and strength properties of soils.The impact of time and temperature changes on soil behavior.Providing an understanding of soil behavior, a fundamental requisite to a wide variety of engineering applications including foundation design and construction, earthwork construction, and geotechnical engineering, Fundamentals of Soil Behavior is an essential learning resource for geotechnical and geoenvironmental engineers, geologists, geophysicists, and students studying geotechnical engineering and granular materials.

Geomechanics from Micro to Macro contains 268 papers presented at the International Symposium on Geomechanics from Micro and Macro (IS-Cambridge, UK, 1-3 September 2014). The symposium created a forum for the dissemination of new advances in the micro-macro relations of geomaterial behaviour and its modelling. The papers on experimental investigations show findings from micro-scale experiments, non-destructive imaging, element testing (coarse grained materials, fine grained materials and mixtures), physical model tests and field tests. The subjects of the investigations include particle effects (shape, size and grading), partial saturation, creep and aging, fluid-grain coupling, biological and chemical effects, and thermal effects. The papers on discrete based modelling examine pre- and post-failure behaviour, particle shapes and size effects, particle crushing, dynamic behaviour, bonding effects, fracturing and fragmentation, interface behaviour, and fluid-grain coupling. The contributions on continuum based modelling include stress-strain relationships, multi-scale modelling, multiphase modelling, fluid flow modelling, and numerical modelling based on continuum based models and particle based models. Geomechanics from Micro to Macro will be of interest to academics and engineers involved in granular physics, soil mechanics, rock mechanics, geotechnical engineering and geological engineering.
