Abstract

- A boundary element formulation, which does not require domain inte- gration, is applied for linear elastic cracked structures subjected to inertial loads. The distinct set of equations for coincident nodes on the crack surfaces is obtained by using the displacement boundary equation on one of the crack surfaces and the traction equation on the other. Domain integrals in the elastodynamic equa- tion are transformed into boundary integrals using the dual reciprocity method. Stress intensity factors are calculated by using the path-independent J - integral. Numerical examples of structures subjected to inertial forces are given and the results are com
