Crushing Behavior of Thin-Walled Hexagonal Tubes with Partition Plates

Abstract EN

The crushing behaviour of hexagonal thin-walled tube with partition plates subjected to axial compression is studied by using finite element method.

It is found that, in the crushing process, the folds, which generate along the full length of the tube, come to be crushed simultaneously and the compressive load will not descend, since the compressive load produced in the central part does not descend with the folds forming on outer walls.

Therefore, in order to suppress a fluctuation of the compression load in crushing of the tube and to raise its average compression load, it is an effective method to introduce corner parts, especially corner parts where three plates intersect, in the geometry of the thin-walled tube.
