This article studies the crashing resistance and energy absorption of multi-cell tubes employed in the design of crash boxes in automobiles. The cross-sections and wall thickness significantly influence the tube’s crushing resistance and energy absorption. Specifically, altering the internal wall’s length, also referred to as span ‘e’, results in changes to the tube’s crashworthiness performance. The results of these samples demonstrate that increasing the span ‘e’ from 10 to 30 mm, while keeping the wall thickness ‘t’ constant at 1.2 mm, reduces the peak crushing load (PCL) from 91.39 kN to 89.65 kN and increases the specific energy absorption (SEA) from 11.51 kJ/kg to 12.12 kJ/kg. The T1_1.2_30 tube achieves the highest SEA and the lowest PCL indices.
