We congratulate Marco Schmidt on his doctorate

4 December 2020

Marco Schmidt, a former research assistant at our institute (structural mechanics), successfully defended his doctoral dissertation on December 4, 2020. We congratulate him warmly!

The title of his dissertation is:

"Biaxiale Experimente und numerische Simulationen mit neu entwickelten Probekörpern zur Vorhersage der Schädigung und des Versagens duktiler Metalle"
("Biaxial experiments and numerical simulations with newly developed test specimens to predict damage and failure of ductile metals")

The following experts participated: Univ.-Prof. Dr.-Ing. habil. Michael Brünig, Univ.-Prof. Dr.-Ing. habil. Manuela Sander and Prof. Dr.-Ing. Wolfram Volm.

To prevent damage to components and structures and to ensure a high level of operational reliability, predicting the damage and failure behavior of ductile materials using suitable models is of great importance. Various phenomenological or micromechanical models are presented in the literature for this purpose. A key aspect is also representing the behavior as a function of stress triaxiality. Against this background, Mr. Schmidt investigated the damage and failure behavior of ductile materials based on Brünig's continuum damage model using experimental and numerical methods and derived a cracking criterion from it.
