It has been pointed out in a previous paper by the authors [1] that conservative internal moments of a spatial beam are of the so-called fourth kind, and that the rotation variables which are energy-conjugate with these moments are vectorial rotations. Vectorial rotations of a spatial Euler-Bernoull

A co-rotational total Lagrangian finite element formulation for the geometrically nonlinear dynamic analysis of spatial Euler beam with large rotations but small strain, is presented. The nodal coordinates, displacements, rotations, velocities, accelerations, and the equations of motion of the stru
The co-rotational technique is described for the three-dimensional analysis of continua. The technique exploits the proven technology of the best continua elements for linear analysis which are embedded into a formulation that applies an element-attached local co-ordinate frame that continuously mov
The work presented in this paper is based on an existing comprehensive formulation for rotating #exible systems. In the existing formulation the #exible degrees of freedom (d.o.f.) are represented by an analytically computed modal basis and the coupling matrices between the rigid-and the #exible-bod
