FEM-remeshing technique applied to crack growth problems

The remeshing option of the commercial FE-code ABAQUS is used to study crack propagation in elastic-plastic materials. Propagation is accomplished with a combination of remeshing and nodal relaxation. The results are compared with analyses using nodal release only. Substantial crack growth is achiev...

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