Abstract: Focused on wood and nacre, the strengthening and toughening microcosmic mechanisms of natural composite is reviewed, And a new-type bursting layer structure, honeycomb sandwich steel tube filled with concrete is presented based on the bionics theory, whose anti-penetration mechanism is discussed taking a single short steel filled with concrete component as object. Employing the software, LS-DYNA, this process is simulated and the results indicates that the proposed biomimetic laminar defense structure obviously outperforms than the normal one of common concrete in anti-penetration.
Keywords: anti-penetration characteristics, steel tube confined conc rete, biomimetic design, numerical simulation.
