Sažetak
The paper presents an algorithm for the buckling analysis of thin-walled laminated composite beam-type structures. A one-dimensional finite element is employed subject to the assumptions of large displacements, large rotation effects but small strains. The geometric stiffness matrix of thin-walled beam finite element is derived. Stability analysis is performed in a load deflection manner using the co-rotational formulation. The cross-section mid-line contour is assumed to remain not deformed in its own plane and the shear strains of the middle surface are neglected. The laminates are modelled on the basis of classical lamination theory. The results are validated on test examples.
