Book excerpt: Pour résoudre les problèmes de diffraction électromagnétiques tridimensionnels, d'ondes harmoniques par des diélectriques hétérogènes, nous présentons trois formulations variationnelles différentes couplant des éléments finis de volume et des formules de représentation intégrale, ainsi que les espaces correspondants. Nous prouvons l'existence et l'unicité sous certaines hypothèses, et étudions en particulier l'influence des valeurs propres. Pour faire l'approximation numérique, nous utilisons des éléments finis de volume H(ROT) ainsi que des éléments finis de surface H(DIV), et nous prouvons existence et convergence pour la solution d'une des trois formulations approchées. Pour illustrer l'influence des valeurs propres, ainsi que les résultats de convergence, nous présentons quelques résultats numériques qui confirment l'étude théorique. Le dernier chapitre est quant à lui consacré à l'étude des modes propres de cavité résonnante approximes par éléments finis de volume, et au taux de convergence des valeurs calculées.

Book Synopsis Résolution numérique des équations de Maxwell harmoniques par une méthode d'éléments finis discontinus by : Philippe Helluy
Download or read book Résolution numérique des équations de Maxwell harmoniques par une méthode d'éléments finis discontinus written by Philippe Helluy and published by . This book was released on 1994 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse porte sur la résolution théorique et numérique des équations de Maxwell dans le domaine temporel ou fréquentiel. Dans une première partie, on démontre l'existence et l'unicité mathématique de la solution du problème d'évolution. On s'intéresse également au comportement asymptotique en temps de cette solution lorsque le second membre des équations est sinusoïdal en temps. L'approche utilisée fait appel à la théorie des systèmes hyperboliques linéaires du premier ordre, au théorème de Hille-Yosida, aux principes d'amplitude limite et d'absorption limite, ainsi qu'à des théorèmes de traces (dans le cas du problème aux limites). Dans un second temps, on développe une approximation par éléments finis discontinus du problème fréquentiel, basée sur une décomposition de la matrice des flux en partie positive et négative (méthode de Flux-Splitting). Cette approche autorise l'utilisation de maillages totalement déstructurés. Une étude d'erreur lorsque le pas h du maillage tend vers zéro est proposée. Un algorithme itératif de résolution du problème discret, basé sur une décomposition de domaine sans recouvrement, est ensuite décrit. On démontre sa convergence vers l'unique solution discrète. L'implémentation sur un ordinateur à architecture massivement parallèle (ipsc 860) a été réalisée. Enfin, on construit une équation intégrale adaptée à la méthode, pour la résolution des problèmes en domaine non borné. Des expériences numériques sont décrites dans le cas d'éléments finis de type p#0 (approximation constante par élément).

Book Synopsis Bogoliubov-de Gennes Method and Its Applications by : Jian-Xin Zhu
Download or read book Bogoliubov-de Gennes Method and Its Applications written by Jian-Xin Zhu and published by Springer. This book was released on 2016-06-21 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to provide an elementary yet systematic description of the Bogoliubov-de Gennes (BdG) equations, their unique symmetry properties and their relation to Green’s function theory. Specifically, it introduces readers to the supercell technique for the solutions of the BdG equations, as well as other related techniques for more rapidly solving the equations in practical applications. The BdG equations are derived from a microscopic model Hamiltonian with an effective pairing interaction and fully capture the local electronic structure through self-consistent solutions via exact diagonalization. This approach has been successfully generalized to study many aspects of conventional and unconventional superconductors with inhomogeneities – including defects, disorder or the presence of a magnetic field – and becomes an even more attractive choice when the first-principles information of a typical superconductor is incorporated via the construction of a low-energy tight-binding model. Further, the lattice BdG approach is essential when theoretical results for local electronic states around such defects are compared with the scanning tunneling microscopy measurements. Altogether, these lectures provide a timely primer for graduate students and non-specialist researchers, while also offering a useful reference guide for experts in the field.

Book excerpt: W S HALL School of Computing and Mathematics, University of Teesside, Middlesbrough, TS1 3BA UK G OLIVETO Division of Structural Engineering, Department of Civil and Environmental Engineering, University of Catania, Viale A. Doria 6, 95125 Catania, Italy Soil-Structure Interaction is a challenging multidisciplinary subject which covers several areas of Civil Engineering. Virtually every construction is connected to the ground and the interaction between the artefact and the foundation medium may affect considerably both the superstructure and the foundation soil. The Soil-Structure Interaction problem has become an important feature of Structural Engineering with the advent of massive constructions on soft soils such as nuclear power plants, concrete and earth dams. Buildings, bridges, tunnels and underground structures may also require particular attention to be given to the problems of Soil-Structure Interaction. Dynamic Soil-Structure Interaction is prominent in Earthquake Engineering problems. The complexity of the problem, due also to its multidisciplinary nature and to the fact of having to consider bounded and unbounded media of different mechanical characteristics, requires a numerical treatment for any application of engineering significance. The Boundary Element Method appears to be well suited to solve problems of Soil- Structure Interaction through its ability to discretize only the boundaries of complex and often unbounded geometries. Non-linear problems which often arise in Soil-Structure Interaction may also be treated advantageously by a judicious mix of Boundary and Finite Element discretizations.

Book Synopsis Mechanics of Ballasted Rail Tracks by : Buddhima Indraratna
Download or read book Mechanics of Ballasted Rail Tracks written by Buddhima Indraratna and published by CRC Press. This book was released on 2005-08-11 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the authors discuss testing of ballast, including the strength, deformation and degradation aspects of fresh and recycled ballast under monotonic and cyclic loading. The effectiveness of geosynthetics in stabilising recycled ballast has also been examined. A new stress-strain constitutive model for ballast incorporating particle breakage is presented. Finally, a new range of particle gradations, balancing the strength and permeability requirements, has been proposed for future rail tracks. This book is intended as a reference text for final year civil engineering students and postgraduates, and for practicing railway engineers with the task of modernizing existing designs.
