Key Points

Bionic thin-walled structures inspired by glass sponges demonstrate superior energy absorption, achieving high strength-to-weight ratios under axial loading.
Specific energy absorption increased by 78.64% in the bionic tube relative to equal-mass four-X designs, confirming enhanced crashworthiness.
Assessment using experiments and simulations across bilinear tubes confirms viable folding modes, highlighting versatile lattice structure engineering.
