Summary

A geometrically nonlinear beam model suitable to describe complex three-dimensional effects arising from non-uniform warping including non-standard in-plane distortions of the cross-section or from the anisotropy and heterogeneity of the material is presented. Each section is endowed with a corotational frame where statics and kinematics are described using a refined linear elastic model which exploits a semi-analytical solution of the Cauchy continuum problem based on a finite element discretization of the cross-section. The stress field in this way is fully three-dimensional, permitting the recovery of the standard Saint Venant solution or its generalization to inhomogeneous and anisotropic materials, while some additional relevant strain modes of the crosssection are evaluated in a simple way. Buckling analysis results are presented and compared with reference solutions obtained using the commercial code ABAQUS.
