on the effect of different ratio of perforation’s diameters on crashworthiness of steel cans

in this paper, structures are investigated by collapse test and loading will be quasi-static. as is evident, doing an experiment always containing cost and time. so by designing the experiment can be spending the minimum cost and time،get the most information about the process. this structure was investigated by two parameters side’s ratio and slot location. the results showed that the maximum value of energy absorption parameters were achieved in side’s ratio 2 and perforation’s diameter 0.5. the reported results are 1.47 kj for absorbed energy, 19.61 kn for mean crushing load, 15.05 kj/kg for specific energy absorption and 37.5 kn for peak load.
