Kurzbeschreibung (Abstract)
Ductile crack growth is examined by a simplified damage model, where the damage zone is localized in front of the crack tip. The continuum damage model is implemented into a Dugdale-Barenblatt-type cohesive zone model. The elastic-plastic crack growth problem is solved by the Finite Element Method. A good agreement of the numerical results with experimental and numerical data available in literature is obtained. Preventing the occurrence of a process zone with vanishing width, mesh independent results are obtained for stationary cracks as well as for growing cracks.
