| Abstract: | By use of the finite element software LS-DYNA,under the same blast wave loading, numerical simulation is done for the response of common steel defensive structure and steel defensive structure with interlayer of aluminum foam. Comparative analysis is made with numerical simulation's result of the two defensive structures. The result shows that steel defensive structure with interlayer of aluminum foam is of good shock attenuation characteristics. It is proved that the new defensive structure is worth applying in the anti-blast design of the entrance of tunnels. |
