This analysis demonstrates flexural buckling in extension-twist coupled beams, indicating the impact of shear coupling and boundary conditions.
A study of the flexural buckling of single-cell extension-twist coupled beams under axial compression is presented. The analysis is based on a recently developed geometrically non-linear thin walled beam theory. The effects of direct transverse shear and the parasitic bending-transverse shear coupling as well as those of different boundary conditions and ply-angles are discussed.
