The paper presents a means of determining the non-linear sti!ness matrices from expressions for the "rst and second variation of the Total Potential of a thin-walled open section "nite element that lead to non-linear sti!ness equations. These non-linear equations can be solved for moderate to large
Buckling byFlexure and Torsion under Central Thrust.--Let us consider now the general case of buckling where, under central thrust, not only torsion but also bending of the axis of the compressed bar occurs. We assume that x and y are the principal centroidal axes of the cross section of the bar and
