Abstract
The remeshing option of the commercial FE-code ABAQUS is used to study crack propagation in elastic-plastic tnaterials. Propagation accomplished with a coztzbination ot remeshing and nodal relaxation. The results are compared with analyses usine nodal release only. Substantial crack growth is achieved with less computer time and higher accuracy than in conventional FE analysis.
