文摘

Experimental natural frequencies and buckling loads of aluminium thin-walled beam. Beam with slightly non-symmetric cross-section under axial force. Non-vanishing shear-torsion and flexure-torsion coupling terms. New end constraint efficient to control displacement, rotation, twist and warping. In-house finite difference code able to read the slight non-symmetry.
