The habilitation thesis is focused on a demonstration of advanced experimental methods for the investigation of the auxetic
metamaterial response on high-strain rate loading. Several types of auxetic structures manufactured using an additive manufacturing technique are introduced.
These structures are tested using a Split Hopkinson Pressure Bar (SHPB) technique and its modifications at different strain-rates. The design and properties of
the SHPB apparatus and an Open Hopkinson Pressure Bar (OHPB) as well as the proper instrumentation are described in the thesis. Moreover, the supplementary
experimental campaigns, such as testing at elevated and reduced temperatures or penetration testing, are mentioned. The final passage of the habilitation thesis is
an introduction of the very unique and advanced facilities for the high-speed X-ray imaging of the high-strain rate or intermediate strain-rate testing that are currently
implemented at the Department of Mechanics and Materials.
