Mixed Finite Elements for Geometrically Exact Beams using Discontinuous Rotations and Discrete Curvature
Alexander Humer, Ivo Steinbrecher, Astrid Pechstein
We propose a novel mixed finite-element formulation for geometrically exact (Simo--Reissner) beams that introduces the moment vector as additional independent field. The specific m…

Direct coupling of continuum and shell elements in large deformation problems
Astrid Pechstein, Michael Neunteufel
In many applications, thin shell-like structures are integrated within or attached to volumetric bodies. This includes reinforcements placed in soft matrix material in lightweight…
