Sažetak
The paper presents a novel geometrically exact spatial beam finite element derived from the so-called fixed-pole approach. While utilising the standard Galerkin discretisation, these elements turn out to have non-standard degrees of freedom which are a combination of translations and rotations. If these unknowns are interpolated using Lagrange polynomials the discretised strain measures turn out to be strain non-invariant. In this work a remedy to this problem is presented.
