A geometrically exact spatial beam finite element based on the fixed-pole approach

A spatial geometrically exact finite element based on the fixed-pole approach of an arbitrary order is presented. In contrast to the original formulation by Bottasso and Borri, this formulation uses standard kinematic unknowns and is therefore combinable with standard finite elements. Preliminary results show that when updating displacements and rotations at integration points, this formulation may yield more accurate results.
