  • Kinematically exact beam finite elements based on quaternion algebra [Elektronski vir]
    Zupan, Eva ; Saje, Miran ; Zupan, Dejan, mehanik
    Rotations in three-dimensional Euclidean space can be represented by the use of quaternions numerically efficient and robust. In the present approach, rotational quaternions are used as the primary ... quantities to describe the rotational degrees of freedom for static and dynamic analysis of geometricallynonlinear beam-like structures. The classical concept of parametrization of the rotation matrix by the rotational vector is thus completely abandoned. The consistent governing equations of the beam in terms of the quaternion algebra are presented and several quaternion-based numericalimplementations are discussed.
