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 ยฎnite element, large displacement formulation of static elasticยฑplastic analysis of slender arbitrarily curved planar beams is presented. Non-conservative and dynamic loads are at present not included. The Bernoulli hypothesis of plane cross-sections is assumed and the eect of shear strains is neg
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
