Self-avoiding fluid deformable surfaces
Maik Porrmann, Sören Bartels, Axel Voigt
We propose a numerical method for fluid deformable surfaces governed by surface Stokes flow and Helfrich bending energy under active growth, aiming to model shape evolution of the…

Babuška's paradox in a nonlinear bending-folding model
Sören Bartels, Andrea Bonito, Peter Hornung +1
The BabuÅ¡ka or plate paradox concerns the failure of convergence when a domain with curved boundary is approximated by polygonal domains in linear bending problems with simply sup…

Numerical simulation of a fine-tunable Föppl-von Kármán model for foldable and bilayer plates
Sören Bartels, Bernd Schmidt, Philipp Tscherner
A numerical scheme is proposed to identify low energy configurations of a Föppl-von Kármán model for bilayer plates. The dependency of the corresponding elastic energy on the in…
