Formulations of displacement discontinuity method for crack problems based on boundary element method

In the current research, formulations of the displacement discontinuity method (DDM) for crack problems based on boundary element method (BEM) are proposed in finite domain. Four different boundary element methods, i.e., the conventional direct displacement boundary element method (CBEM), the hyper-singular traction direct boundary element (HBEM), the displacement discontinue indirect boundary element method (DD-IBEM), and the fictitious stress...
