Available in PDF, EPUB and Kindle. Book excerpt: This book describes the development of a constitutive modeling platform for soil testing, which is one of the key components in geomechanics and geotechnics. It discusses the fundamentals of the constitutive modeling of soils and illustrates the use of these models to simulate various laboratory tests. To help readers understand the fundamentals and modeling of soil behaviors, it first introduces the general stress–strain relationship of soils and the principles and modeling approaches of various laboratory tests, before examining the ideas and formulations of constitutive models of soils. Moving on to the application of constitutive models, it presents a modeling platform with a practical, simple interface, which includes various kinds of tests and constitutive models ranging from clay to sand, that is used for simulating most kinds of laboratory tests. The book is intended for undergraduate and graduate-level teaching in soil mechanics and geotechnical engineering and other related engineering specialties. Thanks to the inclusion of real-world applications, it is also of use to industry practitioners, opening the door to advanced courses on modeling within the industrial engineering and operations research fields.

This book was released on 2008-12-16 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains 23 papers presented at the ECCOMAS Multidisciplinary Jubilee Symposium - New Computational Challenges in Materials, Structures, and Fluids (EMJS08), in Vienna, February 18–20, 2008. The main intention of EMJS08 was to react adequately to the increasing need for interdisciplinary research activities allowing ef?cient solution of complex problems in engineering and in the applied sciences. The 15th anniversary of ECCOMAS (European Community on Computational Methods in Applied Sciences) provided a suitable frame for taking the afo- mentioned situation into account by inviting distinguished colleagues from d- ferent areas of engineering and the applied sciences, encouraging them to choose multidisciplinary topics for their lectures. The main themes of EMJS08 have a long tradition in engineering and in the applied sciences: materials, structures, and ?uids. The solution of scienti?c pr- lems involving ?uids together with solids and structures, not to forget the materials the structures are made of, is of paramount importance in a technical world of rapidly increasing sophistication, referred to as the Leonardo World by the eminent German philosopher Ju ̈rgen Mittelstraß. More recently, the main themes of EMJS08 have gained considerable mom- tum, owing to signi?cant progress in nanotechnology. It enables resolution of a multitude of materials into their micro- and nanostructures. Covering aspects such as • Physical and chemical characterization • Multiscale modeling concepts, continuum micromechanics, and computational homogenization, as well as • Applications in various engineering ?elds the individual contributions to this book ?ow along different tracks of ?uids, materials, and structures.

Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes research being pursued within the Research Unit FOR 2089, funded by the German Research Foundation (DFG), the goal of which is to develop the scientific base for a paradigm shift towards dimensioning, structural realization and maintenance of pavements, and prepare road infrastructure for future requirements. It provides a coupled thermo-mechanical model for a holistic physical analysis of the pavement-tire-vehicle system: based on this model, pavement structures and materials can be optimized so that new demands become compatible with the main goal – durability of the structures and the materials. The development of these new and qualitatively improved modelling approaches requires a holistic procedure through the coupling of theoretical numerical and experimental approaches as well as an interdisciplinary and closely linked handling of the coupled pavement-tire-vehicle system. This interdisciplinary research provides a deeper understanding of the physics of the full system through complex, coupled simulation approaches and progress in terms of improved and, therefore, more durable and sustainable structures.

Download or read book Generalized Bounding Surface Model for Cohesive Soils written by Andres E. Nieto Leal and published by . This book was released on 2016 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Constitutive models have been developed to simulate the soil response under different loading conditions. Within the wide spectrum of these conditions, earthquakes have been of interest to the research community worldwide. Traditionally, researchers have largely focused on simulating the response of cohesionless soils. By contrast, far less research has been done on simulating the response of cohesive soils subjected to cyclic loading. Consequently, certain issues associated with the simulation of such response are still being addressed. A review of experimental results has identified several key characteristics of cyclically loaded cohesive soils that any rational mathematical simulation must account for. Accordingly, the scope of this dissertation is the development of an improved and generalized elastoplastic bounding surface model that is suitable for simulating the general response of cohesive soils, with emphasis on cyclic loading. In its most general form, the Generalized Bounding Surface Model (GBS-Model) for cohesive soils is a fully three-dimensional, time-dependent model that accounts for both inherent and stress induced anisotropy. The rotational hardening law and the shape hardening function were chosen after a thorough review of past modeling practices; in both cases, the selected functional form simplified earlier versions of the bounding surface model without compromising the GBS-Model's predictive capabilities. In addition, to better simulate the behavior of cohesive soils exhibiting softening, the model employs a non-associative flow rule. To more accurately simulate the behavior of cohesive soils subjected to cyclic loading, the model uses a robust general methodology for locating the projection center at any point in stress invariant space, within or on the bounding surface, associated with the radial mapping rule that results in a Lode angle dependency not only of the plastic potential surface but of the bounding surface as well. If all of the aforementioned features of the GBS-Model are not deemed necessary for the simulation of a particular soil and boundary conditions, then the model can be suitably simplified making it appropriate for adaptive model simulations that can be tailored (through suitable simplifications) to the specific nature of a boundary value problem. For instance, the GBS-Model can be adaptively changed from a complex and more accurate version (e.g., anisotropic with non-associative flow rule) to a simpler one (e.g., isotropic with associative flow rule); thus, minimizing errors and increasing numerical efficiency, thereby reducing computational cost. Finally, a wide range of cohesive soils is used to compare experimental results with the numerical simulations. Besides, a sensitivity analysis, showing how the new parameters influence the simulations, is also presented.

This book was released on 2005-12-28 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings document the various papers delivered and partially presented at the International Conference “From experimental evidence towards numerical modeling of unsaturated soils,” which was held in Weimar (Germany) during 18-19 September 2003. The conference was organized under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) and the National German G- technical Society (DGGT). The need to understand the behavior of unsaturated soils is becoming exclusively - sential for the geotechnical engineers and designers. In the last three decades many - searchers have made significant contribution to the understanding of the unsaturated soil mechanics. Nevertheless, application of the subject to variety of new problems still - quires our attention. This International conference is a mere attempt to unite researchers and engineers in geotechnical engineering and to discuss about the problems associated with the unsaturated soils. Doing so the objectives of these lecture notes are as follows: - to promote unsaturated soil mechanics for practical application, - to exchange experiences in experimental unsaturated soil mechanics and numerical modeling, - to discuss application of unsaturated soil mechanics to variety of problems. In other words, we could also name these two volumes as “From theory to daily pr- tice”. I would like to extend my deep sense of appreciation as the editor and the Head of the organizing committee, to many persons who have contributed either directly or indirectly to organize the International conference and to finalize these proceedings.
