• The diamond pattern was introduced into thin-wall tubes to reduce the initial peak forces during axial crushing processes. The finite element method was used to analyze the performance of diamond-patterned origami tubes with square cross sections. The results show that the diamond-patterned origami tubes have lower initial peak forces but more steady crushing processes, in comparison with the corresponding straight-wall tubes. The critical conditions were obtained for the origami tubes with buckling modes agreeing with the diamond pattern creases. The relationships between the sector angle of the origami tube and the initial peak force as well as the mean crushing force under axial impact were also studied.
