Talk by Markus Königsberger on Multiscale Micromechanics Modeling: From Complex Microstructures to Macroscopic Mechanical Properties
Time: Wednesday 27 April 2022, 11:00 am, online.
Modeling the mechanical behavior of heterogeneous materials requires capturing the underlying basic mechanisms occurring at microscopic or nanoscopic scales. Micromechanical multiscale homogenization in the framework of continuum micromechanics is a powerful and efficient vehicle for establishing the sought micro-to-macro links and for predicting thermo/poro/visco-elastic properties and material failure. In this talk, some basics of micromechanics homogenization theory are introduced and multiscale models for different materials (including alkali-activated concrete and bio-composites) are presented. The models are then evaluated based on experiment-informed mechanical, chemical, and morphometrical properties of the microstructure. The prediction results are compared to experimental data. Unique insights into the link between microstructure and macro-behavior are finally highlighted.
Markus Königsberger is a PostDoc researcher at the Institute for Materials and Structures at TU Wien in the team of Prof. Josef Füssl and at the BATir Department at Université libre de Brussels in the Team of Prof. Stéphanie Staquet. His doctoral graduation as Ph.D. in 2017 at TU Wien was awarded the highest possible (Promotio sub auspiciis). In 2018, he received a Post-Doctoral research grant (chargé de recherches) from the Belgian Fund for Scientific Research. His research focuses on the development of multiscale material models for predicting the thermo-mechanical properties of sustainable building materials (biocomposites, geopolymers, blended cements, recycled concretes, clay bricks) as well as on their experimental characterization.
