Abstract: Thin-walled tubular structures have been emerged as efficient impactenergy absorbing members to mitigate the adverse effects of impact forcesand protect occupants from injury during collision events. From theexisting literature, it is evident that, among the other geometryconfiguration, cylindrical tubes have attracted the attention of researchers newlinein the recent decades due to their light weight, high energy absorptioncapacity and ease of fabrication. Despite the cylindrical tubes have higherenergy absorption capacity, high initial peak force is a major shortcomingwhen they are subjected to axial impact. According to the injury criteria(e.g. HIC), excessively high initial peak force is undesirable because it willlead to a large deceleration with much enhanced probability of damage andhuman fatality.Though various triggering methods (holes, grooves, dents, patternsetc.) have been proposed in the previous literature with the aim of reducing newlinethe initial peak forces, these kinds of geometrical discontinuities willchange or decrease the stiffness of the structure under impact loadingconditions. It also has a drawback of reduced energy absorption capacity newline newline
