Barodesy is a constitutive model for granular materials such as sand and clay. It is based on the asymptotic behaviour of granular media at a constant deformation rate. In this work the existing sand version of Barodesy is improved. For this purpose, the underlying scalar equations are simplified using different concepts from soil mechanics. The improved version is also compared with laboratory tests and different elastoplastic and hypoplastic constitutive relations. Also the stability of slopes and advanced stress paths such as the rotation of the princple stresses are investigated with these models.

Barodesy is a constitutive model for granular materials. It is based on proportional strain and stress paths and the asymptotic behaviour of soil. In this work, an existing relation for proportional strain paths and proportional stress paths is further developed. A modification of barodesy to model clay behaviour is introduced. Common concepts of soil mechanics, such as critical states, barotropy and pyknotropy are comprised.

Zur Lösung geotechnischer Problemstellungen mittels numerischer Methoden ist eine möglichst realitätsnahe mathematische Beschreibung des Bodenverhaltens mit Materialmodellen erforderlich. Bei der Barodesie handelt es sich um eine Gruppe an Materialmodellen, welche auf dem asymptotischen Verhalten des Bodens beruhen. Im Zuge dieser Arbeit wird die Weiterentwicklung der Barodesie für Ton in Bezug auf das Wiederbelastungsverhalten behandelt. Dabei werden sowohl die Aspekte der Steifigkeit im Bereich kleiner Verzerrungen (small-strain stiffness), als auch die Steifigkeitsänderung zufolge der Ãoeberkonsolidierung des Bodens betrachtet. Die hierbei entwickelten Ansätze zu Beschreibung des Bodenverhaltens werden mit Ergebnissen von Laborversuchen und mit den Ergebnissen anderer Materialmodelle verglichen. Zusätzlich wird das erhaltene Materialverhalten anhand der Nachrechnung vereinfachter, typischer geotechnischer Problemstellungen mittels Finite-Elemente Berechnungen aufgezeigt.

This work aims at developing a numerical simulation method, Soft PARticle Code (SPARC). The term textit soft emphasizes that no boundaries between particles are defined and every particle possesses a support consisting of a set of adjacent particles. The polynomial interpolation/approximation method is utilized for the evaluation of spatial derivatives using the information carried by particles in supports. The system of equations consisting of spatial derivatives is solved using an iterative nonlinear solver and the computation of the Jacobian matrix is parallelized. The simulations of laboratory tests have been carried out to show the applications and limitations of the current version of SPARC. In addition to the simulations, laboratory (zig-zag) model tests using fine sand were carried out, in which the cyclic tilt of a retaining wall induces a peculiar motion in the backfill (sand), with closed trajectories (eddies).

It is widely recognized that the degree of development of a science is given by the transition from a mainly descriptive stage to a more quantitative stage. In this transition, qualitative interpretations (conceptual models) are complemented with quantification (numerical models, both, deterministic and stochastic). This has been the main task of mathematical geoscientists during the last forty years - to establish new frontiers and new challenges in the study and understanding of the natural world. Mathematics of Planet Earth comprises the proceedings of the International Association for Mathematical Geosciences Conference (IAMG2013), held in Madrid from September 2-6, 2013. The Conference addresses researchers, professionals and students. The proceedings contain more than 150 original contributions and give a multidisciplinary vision of mathematical geosciences.

This book should illustrate the impact of collaborations between mathematics and industry. It is both an initiative of and coordinated by the German Committee for Mathematical Modeling, Simulation and Optimization (KoMSO). This publication aims at comparing the state of the art at the intersection of mathematics and industry, as well as the demands for future development of science and technology in Germany and beyond. Each contribution addresses the importance of mathematics in innovation by means of introducing a successful cooperation with an industrial partner in order to display the wide range of industrial sectors where the use of mathematics is the crucial factor for success, but also show the variety of mathematical areas involved in these activities. The success stories introduced in this volume will be supplemented by appropriate illustrations. It is the goal of this publication to highlight cooperation between mathematics and industry as a two-way technology and knowledge transfer, providing industry with solutions and mathematics with new research topics and inspiring new methodologies.

A Primer to Theoretical Soil Mechanics is about adapting continuum mechanics to granular materials. The field of continuum mechanics offers many fruitful concepts and methods, however there is declining interest in the field due to its complex and fragmented nature. This book's purpose is therefore to facilitate the understanding of the theoretical principles of soil mechanics, as well as introducing the new theory of barodesy. This title argues for barodesy as a simple alternative to the plasticity theory used currently and provides a systematic insight into this new constitutive model for granular materials. This book therefore introduces a complex field from a fresh and innovative perspective using simple concepts, succinct equations and explanatory sketches. Intended for advanced undergraduates, graduates and PhD students, this title is also apt for researchers seeking advanced training on fundamental topics.
