Boundary Elements: International Conference Proceedings

Covering state-of-the-art developments in this field of engineering analysis, this volume consists of the papers presented at an international conference devoted to the boundary element method. It addresses areas of active research related to the BEM community, such as meshless techniques, advanced formulations and high performance computing. Further work in the dual reciprocity method is also discussed. Other papers reflect late-20th century advances in fluid dynamics, fracture and damage mechanics, acoustics and electromagnetism, while there is also a section on the industrial implementation of the technique, and the way in which it can be used as a tool.
