Augmented Lagrangian and operator-splitting methods in nonlinear mechanics by R Glowinski ( )
11 editions published in 1989 in English and held by 461 WorldCat member libraries worldwide
A need for a deeper understanding of the convergence properties of augmented Lagrangian algorithms and of their relationship to operator-splitting methods such as alternating-methods direction and the development of more efficient algorithms prompted the authors to write this book. The volume is oriented to applications in continuum mechanics. This volume deals with the numerical simulation of the behavior of continuous media by augmented Lagrangian and operator-splitting methods (coupled to finite-element approximations). It begins with a description of the mechanical and mathematical frameworks of the considered applications as well as a general analysis of the basic numerical methods additionally used to study them. These ideas are then applied to specific classes of mechanical problems
Numerical analysis of viscoelastic problems by Patrick Le Tallec ( Book )
9 editions published between 1990 and 1997 in English and French and held by 191 WorldCat member libraries worldwide
Numerical methods in sensitivity analysis and shape optimization by Emmanuel Laporte ( Book )
7 editions published between 2002 and 2003 in English and held by 138 WorldCat member libraries worldwide
Sensitivity analysis and optimal shape design are key issues in engineering that have been affected by advances in numerical tools currently available. This book, and its supplementary online files, presents basic optimization techniques that can be used to compute the sensitivity of a given design to local change, or to improve its performance by local optimization of these data. The relevance and scope of these techniques have improved dramatically in recent years because of progress in discretization strategies, optimization algorithms, automatic differentiation, software availability, and the power of personal computers. Key features of this original, progressive, and comprehensive approach: * description of mathematical background and underlying tools * up-to-date review of grid construction and control, optimization algorithms, software differentiation and gradient calculations * practical solutions for implementation in many real-life problems * solution of illustrative examples and exercises * basic mathematical programming techniques used to solve constrained minimization problems are presented; these fairly self-contained chapters can serve as an introduction to the numerical solution of generic constrained optimization problems * supplementary online source files and data; readers can test different solution strategies to determine their relevance and efficiency * supplementary files also offer software building, updating computational grids, performing automatic code differentiation, and computing basic aeroelastic solutions Numerical Methods in Sensitivity Analysis and Shape Optimization will be of interest to graduate students involved in mathematical modeling and simulation, as well as engineers and researchers in applied mathematics looking for an up-to-date introduction to optimization techniques, sensitivity analysis, and optimal design. The work is suitable as a textbook for graduate courses in any of the topics mentioned above, and as a reference text
Maximum principles and application to the analysis of an explicit time marching algorithm by Patrick Le Tallec ( Book )
3 editions published in 1996 in English and held by 78 WorldCat member libraries worldwide
In this paper we develop local and global estimates for the solution of convection-diffusion problems. We then study the convergence properties of a Time Marching Algorithm solving Advection-Diffusion problems on two domains using incompatible discretizations. This study is based on a De-Giorgi-Nash maximum principle
Convergence analysis of domain decomposition algorithms with full overlapping for the advection-diffusion problems by Patrick Le Tallec ( Book )
3 editions published between 1994 and 1996 in English and held by 77 WorldCat member libraries worldwide
The aim of this paper is to study the convergence properties of a Time Marching Algorithm solving Advection-Diffusion problems on two domains using incompatible discretizations. The basic algorithm is first presented, and theoretical or numerical results illustrate its convergence properties

Domain decomposition methods for large linearly elliptic three dimensional problems by Patrick Le Tallec ( Book )
1 edition published in 1990 in English and held by 5 WorldCat member libraries worldwide
This algorithm involves the solution of Dirichlet and of Neumann problems, defined on each subdomain and which can be solved in parallel. This method has been implemented on a CRAY 2 computer using multitasking and on an INTEL hypercube. It was tested on a large scale, industrial, ill-conditioned, three dimensional linear elasticity problem, which gives a fair indication of its performance in a real life environment. In such situations, the proposed method appears operational and competitive on both machines: compared to standard techniques, it yields faster results with far less memory requirements."

MODELISATION MATHEMATIQUE ET NUMERIQUE DES TRANSFERTS D'HUMIDITE EN MILIEUX POREUX by Pierre Nicolas ( Book )
1 edition published in 1992 in French and held by 4 WorldCat member libraries worldwide
L'OBJET DE CETTE ETUDE EST DE DECRIRE LES TRANSFERTS D'HUMIDITE DANS LES MILIEUX POREUX EN INCLUANT LES COUPLAGES THERMIQUES ET LES CHANGEMENTS DE PHASE LIQUIDE-VAPEUR. ON SE PLACE DANS LE CADRE DE LA THERMOMECANIQUE DES MILIEUX CONTINUS. DANS LA MODELISATION, DEUX METHODES SONT PROPOSEES POUR PRENDRE EN COMPTE DES LIAISONS CONVEXES SUR LES VARIABLES INTERNES. L'ORIGINALITE DU MODELE PROVIENT DE LA MODIFICATION DE L'ENERGIE LIBRE DE L'EAU QUI TRADUIT L'INTERACTION DU SQUELETTE SUR L'EAU. LA PRESSION DE LA PHASE GAZEUSE N'EST PAS SUPPOSEE CONSTANTE. LES LOIS PHENOMENOLOGIQUES DE FOURIER, DARCY ET FICK APPARAISSENT COMME DES LOIS DE COMPORTEMENT DEDUITES DU SECOND PRINCIPE. LA LOI DE KELVIN ET L'EXPRESSION DE LA PRESSION CAPILLAIRE NE SONT PLUS CLASSIQUES. UNE DISSIPATION SUR LE TAUX DE CHANGEMENT DE PHASE PERMET D'OBTENIR DES BOUCLES D'HYSTERESIS DYNAMIQUES. DU POINT DE VUE NUMERIQUE, LES INCONNUES DE CALCUL SONT LA TEMPERATURE ET LES MASSES VOLUMIQUES APPARENTES D'AIR, DE VAPEUR D'EAU ET D'EAU LIQUIDE. UNE APPROCHE MIXTE VOLUMES FINIS ET ELEMENTS FINIS EST INTRODUITE DE MANIERE A PRIVILEGIER LE CARACTERE CONSERVATIF ET LA STABILITE DE L'APPROXIMATION. PLUSIEURS SCHEMAS DE DISCRETISATION EN TEMPS SONT COMPARES; LE SCHEMA TOTALEMENT IMPLICITE ASSOCIE A UNE RESOLUTION DU SYSTEME NON LINEAIRE PAR UN ALGORITHME DE NEWTON S'EST AVERE LE PLUS COMPETITIF. DES SIMULATIONS NUMERIQUES SONT PRESENTEES POUR DEUX MILIEUX POREUX: LE MORTIER ET LE SABLE
