Experimental Investigation on the Splitting of Center-Notched Circular Tube

Jafar Rouzegar and Mohammad Karimi
Abstract—Energy absorbers are devices that convert the kinetic energy of impact into other forms of energies. Among different types of energy absorbing mechanism, splitting process is one of the most desired ones due to its steady load during the axial stroke. For the implementation of the splitting process, heavy conical dies are needed, which is a drawback of this method. The present research is an attempt for the introduction of a novel method for axial splitting deformation of thin-walled circular tubes. In the present method, some initial slits are created in the middle length of the tubes and consequently, the dependency of the traditional splitting method on the rigid conical dies is eliminated. These notches were created using a milling machine and electrical discharges (sparks) on the perimeter of the circular brazen tube at the middle length. Then, the specimens were compressed axially under quasi-static condition between two rigid plates. The effects of wall thickness, diameter and length of the tubes, and also, number, length, and width of the notches on the energy absorption parameters of the specimens are investigated.

Index Terms—Center-notched, energy absorber, experimental study, splitting.
