The Boundary Element Method in Engineering Practice

by C. A. Brebbia, Wessex Inst of Technology, Southampton, United Kingdom,



Document Type: Proceeding Paper

Part of: Approximate Methods and Verification Procedures of Structural Analysis and Design

Abstract:

The boundary element method (BEM) provides an excellent basis for the development of integrated design and analysis systems. The technique possesses the advantages of simple model generation, easy to understand requirements, high accuracy, relative insensitivity to mesh refinements and the ability to accurately model the most difficult stress concentration problems. A BEM system that combines these features with close integration with CAD systems, highly automated mesh generation, in-built error estimation and design optimization technology provides a powerful tool for use in engineering analysis and design. This paper discusses BEM discretization, accuracy of results, damage tolerance studies, and other aspects of the subject.
