Experimental Comparison of the Energy Absorption Performance of Traditional Lattice and Novel Lattice Filled Tubes

In this study, β-Ti3Au lattice structure was proposed for the first time in literature as a filling material to increase energy absorption performance of thin-walled tubes. context, performances conventional (i.e., BCC and FCC) filled tubes novel with were compared experimentally. hybrid, FCC hybrid structures produced by additive manufacturing technology using PA2200 powder crushed evaluated considering various crashworthiness criteria such EA SEA. The results showed that are better than traditional particular, has 18.17% 19.39% higher values respectively. These 16.50% 15.66% SEA values, As result, current investigation suggested filler can be significant alternative applications where is critical.
