✦ Synopsis

In this paper the efficiency of the boundary element method (BEM) for the solution of potential and wave propagation problems using BEM-subregions is examined. It will be shown, that the commonly used u-q-continuity technique for the coupling of BEM-subregions, does not always improve the accuracy of the numerical solution. The reason for this behavior, as well as an alternative BEM-formulation based on cardinal (1-0) weighting functions leading to symmetric and positive definite mass-and stiffness-matrices, will be investigated. Numerical results verify the theoretical statements.

In the past the time domain solution of the wave equation has been limited to simplified problems. This was due to the limitations of analytical methods and the capacity of computers to manipulate and store 'large' blocks of spatial information. With the advent of 'super computers' the ability to so

## Abstract This study presents a novel application of the scaled boundary finite element method (SBFEM) to model dynamic crack propagation problems. Accurate dynamic stress intensity factors are extracted directly from the semi‐analytical solutions of SBFEM. They are then used in the dynamic fract
