Congratulations to Dominik Klein for passing his doctoral examination!
2025/10/20
As second PhD student of CPS, Dominik Klein successfully defended his doctoral dissertation entitled “Polyconvex Hyperelasticity with Neural Networks: On Invariant- and Coordinate-Based Models, Benefits and Limitations”!
In his thesis, Dominik Klein developed physics-augmented neural networks (PANNs) for hyperelastic and electro-elastic material modeling that fulfill the constitutive conditions by construction. These models uniquely combine the flexibility of machine learning with mathematical and physical rigor, which ensures accurate, reliable and reasonable behavior, even when trained on small experimental data sets.
Congratulations from Prof. Weeger and all members of the institute to Dominik!
Furthermore, we would like to thank the two external reviewers Prof. Markus Kästner (TU Dresden) and Prof. Daniel Balzani (RU Bochum), as well as all involved national and international cooperators!
While the dissertation still has to be published, you can get an impression of Dominik's work in his latest paper: DOI 10.1016/j.cma.2024.116910.
