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…

Efficient Design of Compliant Mechanisms Using Multi-Objective Optimization
Alexander Humer, Sebastian Platzer
Compliant mechanisms achieve motion through elastic deformation. In this work, we address the synthesis of a compliant cross-hinge mechanism capable of large angular strokes while…
