This part of the project deals with the development of test concepts and experimental techniques for adequately determining the stress-strain relationship of anisotropic, ductile and strain-hardening composites with mineral-based matrices under tensile, compressive and shear impact loads.

The experiments are accompanied by the characterization of defects on the microstructural level (crack propagation) by means of morphological investigations and model descriptions of the mechanical behavior of selected composites.
