✦ Synopsis

The J-integral has been evaluated from finite element analyses of standard test geometries [1,2], for which other known solutions are available, by several authors. These results confirm J to be path independent and to be within 5% of more exact analyses for elastic materials. The errors involved are usually attributed to inaccuracies

## 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
