The use of Green's functions has been considered a powerful technique in the solution of fracture mechanics problems by the boundary element method (BEM). Closed-form expressions for Green's function components, however, have only been available for few simple 2-D crack geometry applications and req

The dual boundary element method coupled with the weight function technique is developed for the analysis of three-dimensional elastostatic fracture mechanics mixed-mode problems. The weight functions used to calculate the stress intensity factors are deÿned by the derivatives of traction and displa
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
