UniSa - IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn this paper a geometrically nonlinear model for studying the lateral global buckling problem of a generic thin-walled composite beams is presented. The model is based on a full second-order deformable beam theory and accounts for axial, flexural, shear, torsional and warping displacements as well as web/flange distortional ways of deformation. Governing nonlinear equations are derived from the Principle of Virtual Displacements. The first numerical results for thin-walled open GFRP profiles under flexural/torsional loads are presented.
