In this paper, a variational technique is described and used to determine the weight functions for three-dimensional dynamic, mixed-mode problems in fracture mechanics. The weight functions required to calculate the stress intensity factors are defined in terms of the derivatives of both traction an
In this paper, the dual boundary element method in time domain is developed for three-dimensional dynamic crack problems. The boundary integral equations for displacement and traction in time domain are presented. By using the displacement equation and traction equation on crack surfaces, the discon
The discretization of the boundary in boundary element method generates integrals over elements that can be evaluated using numerical quadrature that approximate the integrands or semi-analytical schemes that approximate the integration path. In semi-analytical integration schemes, the integration p
