Modern digital material approaches for the visualization and simulation of heterogeneous materials allow to investigate the behavior of complex multiphase materials with their physical nonlinear material response at various scales. However, these computational techniques require extensive hardware resources…
The numerical simulation of microstructure models in 3D requires, due to enormous d.o.f., significant resources of memory as well as parallel computational power. Compared to homogeneous materials, the material hetrogeneity on microscale induced by different material phases demand for adequate computational…
The modeling of crack propagation in plain and reinforced concrete structures is still a field for many researchers. If a macroscopic description of the cohesive cracking process of concrete is applied, generally the Fictitious Crack Model is utilized, where a force transmission over micro cracks is…
Entwicklung eines Algorithmus für ein nichtlineares Materialgesetz für die vollautomatische Rissentwicklungssimulation unter Verwendung der am Institut für Strukturmechanik entwickelten netzfreien Verfahren. In Anlehnung an die Kontinuumsplastizität wird unter Verwendung einer arbeitsbasierten Formulierung…
