## Abstract
This study presents the multi-objective optimisation of empty and foam-filled double circular tubes under pure axial and oblique impact loading conditions. Thin-walled metal tube structures are utilised in vehicular bodies due to the increased energies that can be absorbed by lightweight material structures. Finite element analysis is performed with ABAQUS code, and then confirmed using applicable experimental tests. Optimised designs of crushing parameters, including minimum peak crushing forces and maximum specific energy absorptions, were conducted with Radial Basis and Non-dominated Sorting Genetic Algorithm-II functions. The findings demonstrate that aluminium foam-filled double circular tubes do feature increased crashworthiness over empty, unfilled versions when subject to impact loads.
