Universal norms of partially de Rham -pairs and perfectness in Lubin--Tate Iwasawa theory
Marvin Schneider, Rustam Steingart
We study the behaviour of partially de Rham Selmer groups of -pairs along abelian -adic Lie extensions. In the cyclotomic case we compare them with the universal norms studie…
Reliable training of neural hyperelastic models via full-field data
Konrad Friedrichs, Franz Dammaß, Karl A. Kalina +1
We present a systematic investigation of the robustness and limitations of equilibrium gap-based calibrations for hyperelastic physics-augmented neural networks (PANNs), where we c…
Calibration of neural viscoelastic models via full-field data
Brain M. Riemer, Markus Kästner, Karl A. Kalina
We propose an unsupervised learning framework for calibrating a physics-augmented neural network (PANN) for small-strain viscoelasticity via full-field data. It only requires quant…
On limitations of polyconvexity
Dominik K. Klein, Rogelio Ortigosa, Heinrich T. Roth +4
Polyconvex constitutive modeling is attractive as it guarantees stability of numerical simulations and can improve the generalization behavior of material models. However, in certa…
Advances in polyconvex anisotropic hyperelasticity
Dominik K. Klein, Karl A. Kalina, Rogelio Ortigosa +3
A key challenge in material theory is the formulation of models that satisfy all common mechanical constitutive conditions while retaining sufficient flexibility. In this context,…
