Mixed and Hybrid Finite Element Methods

Author: Franco Brezzi, Michel Fortin | Size: 2.45 MB | Format: DjVu | Quality: Scanner | Publisher: Springer | Year: July 17, 1991 | pages: 350 | ISBN: 0387975829, ISBN-13: 978-0387975825

[Image: 91230023207502694518.jpg]

[Image: info.png]
Research on non-standard finite element methods is evolving rapidly and in this text Brezzi and Fortin give a general framework in which the development is taking place. The presentation is built around a few classic examples: Dirichlet's problem, Stokes problem, Linear elasticity. The authors provide with this publication an analysis of the methods in order to understand their properties as thoroughly as possible.

  Finite Element Methods - Parallel-Sparse Statics and Eigen-Solutions

Finite Element Methods - Parallel-Sparse Statics and Eigen-Solutions

Author: Duc Thai Nguyen | Size: 17.4 MB | Format: PDF | Quality: Original preprint | Publisher: Springer | Year: April 19, 2006 | pages: 531 | ISBN: 0387293302, ISBN-13: 978-0387293301

Finite element methods (FEM), and its associated computer software have been widely accepted as one of the most effective general tools for solving large-scale, practical engineering and science applications. For implicit finite element codes, it is a well-known fact that efficient equation and eigen-solvers play critical roles in solving large-scale, practical engineering/science problems. Sparse matrix technologies have been evolved and become mature enough that all popular, commercialized FEM codes have already inserted sparse solvers into their software. However, a few FEM books have detailed discussions about Lanczos eigen-solvers, or explain domain decomposition (DD) finite element formulation (including detailed hand-calculator numerical examples) for parallel computing purposes. The materials from this book have been evolved over the past several years through the author's research work, and graduate courses.

  Adaptive Finite Element Methods for Differential Equations
Posted by: lisine - 06-09-2012, 10:37 AM - Forum: Finite Element Methods - Replies (2)

Adaptive Finite Element Methods for Differential Equations

Author: Wolfgang Bangerth, Rolf Rannacher | Size: 1.51 MB | Format: DjVu | Quality: Scanner | Publisher: Birkhäuser Basel | Year: April 28, 2003 | pages: 215 pages (125pages available) | ISBN: 3764370092, ISBN-13: 978-3764370091

[Image: 95714929533354569906.jpg]

[Image: info.png]
The key issues are a posteriori error estimation and it automatic mesh adaptation. Besides the traditional approach of energy-norm error control, a new duality-based technique, the Dual Weighted Residual method for goal-oriented error estimation, is discussed in detail. This method aims at economical computation of arbitrary quantities of physical interest by properly adapting the computational mesh. This is typically required in the design cycles of technical applications. For example, the drag coefficient of a body immersed in a viscous flow is computed, then it is minimized by varying certain control parameters, and finally the stability of the resulting flow is investigated by solving an eigenvalue problem. `Goal-oriented' adaptivity is designed to achieve these tasks with minimal cost. At the end of each chapter some exercises are posed in order to assist the interested reader in better understanding the concepts presented. Solutions and accompanying remarks are given in the Appendix.

NOTE:
This is just first 7 chapters + Index.

  Dead Links _ User Help
Posted by: ykhackhack - 06-08-2012, 06:57 AM - Forum: Archive - Replies (1)

Dear Moderators (First of all- Thanks for your hard work here-I personally appreciate it very much)
If I have some spare time and I want to refresh some of the dead links, would not it be very handy to have a section -which the users list the dead links.
We would just go to that section and spend some time to upload a mirror link.
I remember some discussions about link alive button to be available on the threads.
May be this would be helpful mean-time
since it is simple to implement_I think_

  Structural Sensing, Health Monitoring, and Performance Evaluation

Structural Sensing, Health Monitoring, and Performance Evaluation

Author: D. Huston | Size: 6.3 MB | Format: PDF | Quality: Original preprint | Publisher: CRC Press | Year: 2010 | pages: 662 | ISBN: 0750309199

Structural health monitoring (SHM) uses one or more in situ sensing systems placed in or around a structure, providing real-time evaluation of its performance and ultimately preventing structural failure. Although most commonly used in civil engineering, such as in roads, bridges, and dams, SHM is now finding applications in other engineering environments, such as naval and aerospace engineering.
Written by a highly respected expert in the field, Structural Sensing, Health Monitoring, and Performance Evaluation provides the first comprehensive coverage of SHM. The text begins with a review of the various types of sensors currently used in SHM, including point sensors and noncontact systems. Subsequent chapters explain the processing and interpretation of data from a number of sensors working in parallel. After considering issues related to the structures themselves, the author surveys the design of a tailor-made SHM system. He also presents a collection of case studies, many of which are drawn from his own experiences.
Exploring the power of sensors, this book shows how SHM technologies can be applied to a variety of structures and systems, including multistory buildings, offshore wind energy plants, and ecological systems.
