Abstract

- The dual boundary element method (DBEM) and the time domain method are applied for the determination of dynamic stress intensity factors (DSIF) for a general mixed-mode crack problem. The DBEM generates a distinct set of boundary integral equations by applying the displacement equation to one of the crack surfaces and the traction equation to the other. The present method does not require any domain discretisation. The boundary of the body is divided into quadratic elements and quarter-point elements (QPE) are used near the crack tips. The temporal variations of the boundary quantities are either piecewise
