Abstract
The displacement discontinuity method is a type of boundary integral method wherein the fundamental solution used is the static displacement due to a displacement discontinuity on a finite segment in an infinite or semi-infinite medium. The extension of the method to three-dimensional problems is presented together with some examples of its application. It is shown that the use of the Volterra integral to derive the fundamental solution not only clearly identifies the method as a standard boundary integral procedure with a different influence function, but allows the development of several useful extensions of the method in a straightforward manner, and also provides a natural method of linking the method to a finite element computer code.
