Configuration-dependent interpolation in 3D beam elements of arbitrary order

In non-linear 3D beam theory with rotational degrees of freedom a configuration-dependent interpolation of the rotational degrees of freedom appears to be indispensable when tackling the problem of providing a result which is independent of the choice of the beam reference line or invariant to rigid-body rotation. In this work the relationship between the two different aspects of invariance is analysed with a view to providing a methodology for developing higher-order interpolation.
