On the displacement discontinuity method and the boundary element method for solving 3-D crack problems

In this paper, it is shown that the equations of the displacement discontinuity method (DDM) for solving 3-D crack problems are exactly the same as the equations of the boundary element method (BEM) based on the boundary integral equation (BIE). Therefore, many of the results in the BEM research can be applied directly to the DDM, such as the results of analytical integration and fast solution methods, due to this equivalence or connection.
