Werkstoffeinsatz und Bauteilbewertung auf der Basis schädigungsmechanischer Konzepte
FKM 1999
Booklet No. 247 Project No. 201
Abstract:
In this project, novel damage-mechanical methods of material and component evaluation were used and tested in particular for their applicability in mechanical engineering. The focus of the investigations was on ductile failure, which is well described by a material model according to G urson in the form further developed by T vergaard and N eedleman (GTN model). This model is based on the essential mechanisms of ductile damage, namely the formation of cavities at inclusions, their expansion with increasing stress and finally their coalescence, which is accompanied by the formation of a macroscopic crack or its expansion. The model contains parameters that are all of microstructural significance, such as the initial pore volume fo, and the volume of cavity-forming inclusions fN. For the selected applications
