Abstract

The free inversion process of a metal tube is analysed considering a rigid linear strain hardening material and taking into account the changes in the thickness of the tube during plastic deformation. The effects of strain rate and inertia during dynamic inversion are examined. The predictions are compared with experiments and the agreement is seen to be good. While strain rate effects are seen to increase the resistance of the tube to inversion, the effect of inertial forces differ during deformation. In the initial stages inertia increases the inversion force by a considerable extent but reduces the same, by a lesser extent, during the inversion process.
