Triangulations, and more precisely meshes, are at the heart of many problems relating to a wide variety of scientific disciplines, and in particular numerical simulations of all kinds of physical phenomena. In Volume 1, the theoretical foundations relating to triangulations, finite element shape functions and their interpretations as geometric patches were explored. This has made it possible to build tools that make the geometric modeling of any object possible. These elements are used in Volume 2 to treat meshing problems in their different implementations. Meshing, Geometric Modeling and Numerical Simulation 3 offers technical additions to the methods seen in the first two volumes and a significant portion of this book is dedicated to mesh visualization problems and solutions, especially those with a high degree of complexity.

Si l'utilisation des outils informatiques et de nombreux programmes de calculs de structures s'est répandue ces dernières années dans les entreprises et les bureaux d'études, cela ne saurait dispenser les ingénieurs et techniciens d'une bonne maîtrise de la résistance des matériaux, indispensable pour contrôler l'exactitude et la pertinence des résultats : contrôle des ordres de grandeur, validation des hypothèses et des résultats... Cet ouvrage, extrait du cours de résistance des matériaux professé au Centre des Hautes Etudes de la Construction, est destiné aussi bien aux projeteurs, jeunes ingénieurs, élèves ingénieurs et étudiants désireux d'acquérir les mécanismes et ordres de grandeur couramment pratiqués dans le domaine du calcul des structures en bâtiment et en génie civil, qu'aux ingénieurs confirmés souhaitant perfectionner leurs connaissances. Les nombreuses informations relatives à la construction, au bâtiment et au génie civil rassemblés dans ce livre rendront plus aisé le travail du technicien et de l'ingénieur dam l'élaboration et la vérification des projets. Jean Roux, ingénieur ETP - CHEBAP, qui pratique la résistance des matériaux sous une double approche du fait de ses activités d'ingénieur à la SNCF et de professeur à l'ESTP, et au CHEC, a conçu cet ouvrage avec le souci de répondre aux interrogations de l'étudiant et de faciliter la tâche de l'ingénieur.

This volume contains papers and reports from the Conference held in Romania, June 2000. The book covers many topics, for example, place, role and content of geotechnical engineering in civil, environmental and earthquake engineering.

This book focuses on iterative solvers and preconditioners for mixed finite element methods. It provides an overview of some of the state-of-the-art solvers for discrete systems with constraints such as those which arise from mixed formulations. Starting by recalling the basic theory of mixed finite element methods, the book goes on to discuss the augmented Lagrangian method and gives a summary of the standard iterative methods, describing their usage for mixed methods. Here, preconditioners are built from an approximate factorisation of the mixed system. A first set of applications is considered for incompressible elasticity problems and flow problems, including non-linear models. An account of the mixed formulation for Dirichlet’s boundary conditions is then given before turning to contact problems, where contact between incompressible bodies leads to problems with two constraints. This book is aimed at graduate students and researchers in the field of numerical methods and scientific computing.

The 16th ICSMGE responds to the needs of the engineering and construction community, promoting dialog and exchange between academia and practice in various aspects of soil mechanics and geotechnical engineering. This is reflected in the central theme of the conference 'Geotechnology in Harmony with the Global Environment'. The proceedings of the conference are of great interest for geo-engineers and researchers in soil mechanics and geotechnical engineering. Volume 1 contains 5 plenary session lectures, the Terzaghi Oration, Heritage Lecture, and 3 papers presented in the major project session. Volumes 2, 3, and 4 contain papers with the following topics: Soil mechanics in general; Infrastructure and mobility; Environmental issues of geotechnical engineering; Enhancing natural disaster reduction systems; Professional practice and education. Volume 5 contains the report of practitioner/academic forum, 20 general reports, a summary of the sessions and workshops held during the conference.
