A comparative study of energy absorption characteristics and distortions between simple and multi-cell thin-walled tubes with various geometrics are examined. Energy has to disseminate to avoid damage and harm during collisions. To diminish the misfortunes from collision, thin-walled tubes are utilised to dissipate the kinetic energy by deformation. For this analysis, simple and multi-cell tubes with different sections were made from aluminium (Al 3003) sheet and then they are subjected to quasi-static axial crushing. From the results, the energy absorption capacity of various tubes were compared and it shows that multi-cell tubes have more noteworthy than that of simple tubes. Moreover, hexagonal multi-cell tubes were retained as most prominent for higher specific energy absorption. This type of columns was found to be effective one to improve the performance of crashworthiness.
