. LI et al [118] examined the energy absorption behavior of shrink circular tube. As shown in Figures 15 and 16, the 6061-T6 aluminum alloy circular tubes were experimentally shrunken in radial... 19 and 20. LI et al [125, 126] proposed a new structure which combines expansion and splitting of circular metal tube and designed the special metal circular tube and die. Using this system......
