Multiscale Method for the Simulation of Resilience and Fracture Behaviour of Heterogeneous Structures (C05)

• Subject Area: Applied Mechanics, Statics and Dynamics
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 417002380

The objective of the subproject is to extend the multiscale projection method, which is capable of handling localisation effects for heterogeneities and cracks in shell-like structures at finite deformations. This allows for the consideration of the detailed mesoscale behaviour which is significant for failure of the structure within the assessment of the resilience of thin-walled carbon reinforced concrete structures with respect to different external loadings. Crack initiation and propagation are simulated using a combination of the XFEM and gradient-enhanced damage.
