Abstract: A method for modelling arbitrary growth of dynamic cracks without
remeshing is presented. The method is based on a local partition of unity. It
is combined with level sets, so that the discontinuities can be represented
entirely in terms of nodal data. This leads to a simple method with clean data
structures that can easily be incorporated in general purpose software. Results
for a mixed-mode dynamic fracture problem are given to demonstrate the
method.
