3 Overall concept of mechanical characterization
In the framework of this thesis a multitude of experimental and numerical studies on
sandwich structures were performed. With regards to the Building Block Approach and
the previously introduced hierarchy levels (Figure 25) the performed studies can be associated with a specific level. The following chapters 4 to 6 are each dedicated to one of
the three investigated hierarchy levels, constituents, structural elements and sub-components. Within these chapters the investigated materials are firstly summarized before
the experimental setups and results are presented. In case of chapters 4 and 5, the performed experiments are subsequently implemented as virtual tests. This includes numerical studies for the implementation and verification of suitable material models and
modelling approaches. Lastly, the numerical model parameters are calibrated based on
the experimental results. Chapter 6 corresponds to the sub-component level and solely
describes the experiments on different joint configurations. The development of virtual
tests for this top-level is the objective of the proposed virtual testing approach. This is
described in chapter 7 using the experimental results of chapter 6 as reference and for
validation. Figure 28 illustrates the attribution of chapters 4 to 6 to the hierarchy levels.
