Description
Summary:In past few decades, an extensive effort has been made on thin-walled metallic tubes to enhance their deformation and energy absorbing characteristics by focusing different structural patterns. The main aim of this research study is to present the finite element simulation of newly designed thin-walled novel multitubular structures made of extruded aluminium alloy under axial impact loading. Nonlinear impact simulations were performed on the proposed multitublar structures of various configurations using finite element ABAQUS/CAE code. From the outcomes attained, the energy absorption capability of various multitubular structures were compared and it showed that the tritubular structures have absorbed more energy than that of bitubular structures. Moreover, multitubular structure composed of circle, square and triangle were retained as most prominent for higher energy absorption. This type of multitubular structures were found to be effective energy absorbing device to improve the crashworthiness performance during vehicle collisions.
