K. Bhaskar et L. Librescu, BUCKLING UNDER AXIAL-COMPRESSION OF THIN-WALLED COMPOSITE BEAMS EXHIBITING EXTENSION-TWIST COUPLING, Composite structures, 31(3), 1995, pp. 203-212
A study of the flexural buckling of single-cell extension-twist couple
d 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-tra
nsverse shear coupling as well as those of different boundary conditio
ns and ply-angles are discussed.
