Thin-walled beams with a cross-section of arbitrary geometry: Derivation of linear theories starting from 3D nonlinear elasticity

Elisa Davoli

Abstract.

The subject of this paper is the rigorous derivation of lower dimensional models for a nonlinearly elastic thin-walled beam whose cross-section is given by a thin tubular neighbourhood of a smooth curve. Denoting by h and , respectively, the diameter and the thickness of the cross-section, we analyse the case where the scaling factor of the elastic energy is of order , with . Different linearized models are deduced according to the relative order of magnitude of with respect to h.
