Computational Homogenization and Multi-Scale Modelling Employing an Image-Based Approach for the Structural Analysis of Shells

The complementary project C03* focuses on modeling the non-linear material behavior of concrete. While the geometric modeling is dealt with in detail in SP C03, the material behavior is described using conventional models. However, for an improved description of the non-linear behavior of concrete, highly sophisticated and complex material models are required. Therefore, a non-linear constitutive law based on Micro-Plane Models is going to be adapted and implemented in the isogeometric shell formulation from SP C03. The resulting geometrically and materially non-linear shell formulation enables a realistic representation of the mechanical behavior and crack formation of a carbon reinforced concrete shell.
