AN ANALYTICAL INVESTIGATION OF THE CHANGE IN TUBULAR MEMBER BEHAVIOUR RESULTING FROM DAMAGE

In this paper an analytical solution is presented to the problem of a damaged steel tube with a relatively deep local dent (20% of the tube diameter) subjected to combined axial compression and bending. The general purpose finite element program ABAQUS is used for forming the dent and for the subsequent loading of the damaged member; the pre- and post-ultimate behaviour of the member is developed accounting for the nonlinear material and geometric properties. A comparison is carried out between the analytical solution and published experimental evidence. In addition, the analysis is performed on a corresponding non-damaged model with the same geometric and loading parameters, permitting direct evaluation of the reduction in load carrying capacity and the failure characteristics caused by the damage.
