The Laplace transformed boundary element method is used to analyse the transient responses of a three-dimensional crack. The choice of Laplace inversion parameters and the calculation of dynamic stress intensity factors (SIF) are discussed. In order to verify the computation procedure and choose the

The paper presents results obtained by the implementation of a new hybrid Laplace transform/finite element method developed by the authors. The present method removes the time derivatives from the governing differential equation using the Laplace transform and then solves the associated equation wit
In the present paper, a combination of the boundary element method is proposed for calculating the stress intensity factors of two-dimensional crack problems including mixed mode ones. In this method, finite elements are only allocated around a crack tip and boundary elements are used to discretize
Overall comparisons are made for six efficient combinations of the Ritz-Galerkin and finite element methods for solving elliptic boundary value problems with singularities or interfaces. The comparisons are done by using theoretical analysis and numerical experiments. Significant relations among the
