Mechanical Characterization & Modeling

Modeling, Simulation and Testing

This field of competence covers the experimental and simulative analysis of materials, structures, and joints, especially influenced by strain rate and temperature. Key aspects are the evaluation of material properties (parameters, stress-strain-curves,…) and the transfer of this behavior to validated material models for FE simulation. Within these activities, testing procedures are newly developed or optimized. The improvement of energy absorption and structural integrity in tension and bending loaded composite structures and joints is an additional focus in this competence field.
