Dynamic Torsion of Thin-Walled Tubes

Abstract

The following investigation showed that when thin-walled tubes fail in elastic instability from a dynamic torsion; there will be a characteristic deformation in this failure. The characteristic deformation is circumferential buckling waves along the length of the tube. The important result found is that the distance from the point of torsional impact to the location of the buckling is dependent only on the speed at which the torsion is applied and not on the load applied. As the speed of torsion increases, the distance from the point of torsional impact to the location of the buckling decreases.
