Project

SCHARF: Skalenübergreifende Charaktierisierung robuster funktionaler Materialsysteme (scale-bridging characterization of robust functional materials systems)
Programmable mechanical metamaterials process information such as strain and stress through a series of logic steps. This produces a tangible change in their macroscopic mechanical properties. A basis for the logical functions is the design of mesoscopic structures across several hierarchical levels. In my research, I investigate mechanical mechanisms and develop mesostructure designs that are optimized for metal and polymer materials systems with varying mechanical properties (stiffness, elasticity) and manufacturing processes.

Project Outcomes

Quantitative correlations between the manufacturing parameters, the microstructure and the resulting mechanical properties of micro-sized elements, potentially used in programmable material, are established. The correlations build the foundation to custom design programmable materials with the real-world underlying materials properties considered.
