Boundary Methods: Elements, Contours, and Nodes presents the results of cutting-edge research in boundary-based mesh-free methods. These methods combine the dimensionality advantage of the boundary element method with the ease of discretization of mesh-free methods, both of which, for some problems, hold distinct advantages over the finite element method.
After introducing some novel topics related to the boundary element method (BEM), the authors focus on the boundary contour method (BCM)-a variant of the BEM that further reduces the dimensionality of a problem. The final section of the book explores the boundary node method, which combines the BEM with moving least-squares approximants to produce a mesh-free, boundary-only method.
The authors, who are also the primary developers of these methods, clearly introduce and develop each topic. In addition to numerical solutions of boundary value problems in potential theory and linear elasticity, they also discuss topics such as shape sensitivities, shape optimization, and adaptive meshing. Numerical results for selected problems appear throughout the book, as do extensive references.

Author: M. M. Woolfson, G. J. Pert | Size: 13.9 MB | Format:PDF | Quality:Original preprint | Publisher: Oxford University Press | Year: April 8, 1999 | pages: 328 | ISBN: 019850425X, ISBN-13: 978-0198504252
Computer simulation is increasingly used in physics and engineering to predict the probable outcome of experiments and to aid in their interpretation. The methods of simulation are based on a range of numerical techniques for treating ordinary and partial differential equations. Since much of physics can be broken down into a relatively small set of fundamental equations, a few general methods can be widely applied. This text aims to give an introduction to those methods suitable for readers at an undergraduate level and for those studying the subject for the first time at the graduate level. The methods are illustrated with simple programs and problems. The book covers a range of material not available in other introductory texts.

This book provides insight in the mathematics of Galerkin finite element method as applied to parabolic equations. The approach is based on first discretizing in the spatial variables by Galerkin's method, using piecewise polynomial trial functions, and then applying some single step or multistep time stepping method. The concern is stability and error analysis of approximate solutions in various norms, and under various regularity assumptions on the exact solution. The book gives an excellent insight in the present ideas and methods of analysis. The second edition has been influenced by recent progress in application of semigroup theory to stability and error analysis, particulatly in maximum-norm. Two new chapters have also been added, dealing with problems in polygonal, particularly noncovex, spatial domains, and with time discretization based on using Laplace transformation and quadrature.

During the last years, scientific computing has become an important research branch located between applied mathematics and applied sciences and engineering. Highly efficient numerical methods are based on adaptive methods, higher order discretizations, fast linear and non-linear iterative solvers, multi-level algorithms, etc. Such methods are integrated in the adaptive finite element software ALBERTA. It is a toolbox for the fast and flexible implementation of efficient software for real life applications, based on modern algorithms. ALBERTA also serves as an environment for improving existent, or developing new numerical methods in an interplay with mathematical analysis and it allows the direct integration of such new or improved methods in existing simulation software. The book is accompanied by a full distribution of ALBERTA (Version 1.2) on a CD including an implementation of several model problems. System requirements for ALBERTA are a Unix/Linux environment with C and FORTRAN Compilers, OpenGL graphics and GNU make. These model implementations serve as a basis for students and researchers for the implementation of their own research projects within ALBERTA.

Matrix Preconditioning Techniques and Applications
Author: Ke Chen | Size: 4.55 MB | Format:PDF | Quality:Original preprint | Publisher: Cambridge University Press | Year: July 25, 2005 | pages: 592 | ISBN: 0521838282, ISBN-13: 978-0521838283
Preconditioning techniques have emerged as an essential part of successful and efficient iterative solutions of matrices. Ke Chen's book offers a comprehensive introduction to these methods. A vast range of explicit and implicit sparse preconditioners are covered, including the conjugate gradient, multi-level and fast multi-pole methods, matrix and operator splitting, fast Fourier and wavelet transforms, incomplete LU and domain decomposition, Schur complements and approximate inverses. In addition, aspects of parallel realization using the MPI are discussed. Very much a users-guide, the book provides insight to the use of these techniques in areas such as acoustic wave scattering, image restoration and bifurcation problems in electrical power stations. Supporting MATLAB files are available from the Web to support and develop readers' understanding, and provide stimulus for further study. Pitched at graduate level, the book is intended to serve as a useful guide and reference for students, computational practitioners, engineers and researchers alike.

In a large number of concrete structures and structural elements multiaxial compressive stress states occur. As is generally known, these stress states in general have an advantageous effect on the behaviour of the material, compared to the behaviour under uniaxial loading: the load bearing capacity increases and larger deformations are allowable. Unfortunately, this effect has not yet been implemented in the building codes, because there are too many unknowns to describe it in a useful quantitative manner. Therefore insight in the behaviour of concrete under this type of loading is important with respect to safety and deformational capacity of several kinds of concrete structures. At Eindhoven University of Technology (EUT) a research project was started in the early eighties to gain more insight in the failure behaviour of concrete in multiaxial compression. The research described in this thesis is to be regarded as a continuation of the work done earlier at EUT. It deals with several aspects of concrete behaviour in multiaxial compression that were not investigated before or from a different point of view, and intends to answer some remaining questions on the subject.

Modeling Error of Strength of Short Reinforced Concrete Columns
Author: W. Zhou and H. P. Hong | Size: 1 MB | Format:PDF | Quality:Original preprint | Publisher: ACI | Year: 2000 | pages: 9
Abstract:
Probabilistic analyses of the modeling errors of several selected strength prediction models for short reinforced concrete (RC) columns are carried out. The selected strength models include the rectangular stress block model and the stress-strain relation-based theoretical model. A relatively large amount of test data on RC columns is collected from the literature, and the test results are com-pared with the predicted ones obtained from different strength mod-els. Both normal- and high-strength concrete columns are included in this study. The dependency of the modeling errors on concrete compressive strength and the load eccentricity is investigated. Probabilistic analyses of the modeling errors are carried out by using the pseudolikelihood estimation method. Sets of probabilistic models of the modeling errors by considering different analysis approaches are suggested for short RC columns.
