The objective of this book is to formulate, implement and apply the dual boundary element methods in three-dimensional crack problems and linear elastic fracture mechanics. The dual boundary element method has been developed to overcome the ill-conditioning problems associated with the conventional boundary element method. By applying the displacement boundary integral equation on one of the crack surfaces and the traction boundary integral equation on the other, the general mixed mode crack problems can be solved in a single region. The focus of the numerical implementation is on the efficient evaluation of singular and near-singular integrals associated with the formulation. The engineering applications presented in this book concentrate on the simulation and analysis of general mixed mode crack growth in three dimensions.

Looks at the formulation, implementation, and application of the dual boundary element method to three-dimensional crack problems in linear elastic fracture mechanics. To overcome the ill-conditioning problems associated with the conventional boundary element (BEM), the author has applied the displacement boundary integral equation to one of the crack surfaces, and the traction boundary integral equation to the other. This enables general mixed mode crack problems to be solved in a single region. No index. Annotation c. by Book News, Inc., Portland, Or.
