Boundary element method in dynamic crack analysis

Piotr Fedeliński
The boundary element method applications to dynamic fracture mechanics are presented. In the present approach displacement and traction boundary integral equations are used for crack representation. The time-dependent solutions are obtained using the time domain method, integral transform method or dual reciprocity method. The dynamic stress intensity factors are calculated using crack opening displacements and the path-independent J-integral. Some new applications of these methods are also shown.
