Nonlinear models of elastic and visco-elastic onedimensional continuous structures (beams
and cables) are formulated by the authors of this title. Several models of increasing …

The influence of applied axial loads on the fundamental vibration frequency is strictly
connected with the stability analysis of elastic slender beams. For this reason, the correct …

This paper presents the formulation of a three-dimensional beam finite element (FE) that
accounts for cross-section warping and dynamic inertia effects. The model is the extension …

In this paper, stability analysis of thin-walled functionally graded (FG) sandwich box beams
under combined bending and axial forces was carried out. Based on higher order theory that …

Torsion and bending/torsion buckling may occur for compressed thin-walled open profiles
used in engineering and architecture applications. We report experimental results provided …

The experimental natural frequencies and buckling loads of aluminium slightly non-
symmetric thin-Walled beams under axial force are compared with numerical results. A …

In this paper a geometrically nonlinear model for studying the lateral global buckling
problem of a generic thin-walled composite beam is presented. The model is based on full …

A direct non-linear one-dimensional model of an elastic, thin-walled, planar beam is
formulated. The model accounts for changes in shape of the cross-section, in particular the …

This paper presents a study of the formulation of nonlinear beam elements for spatial thin-
walled frame structures. A formulation based on the geometrically exact beam theory is …

We investigate the effects of warping on the dynamic stability of non-trivial equilibrium
configurations for non-symmetric open thin-walled beams. We use a direct one-dimensional …
