| Abstract: | Numerical simulation of spherical projectile hypervelocity impact on double-wall shielding structures is carried out using AUTODYN hydro-codes.The shielding performance of aluminum alloy bumpers is compared with that of the composite material bumpers.The results show that the shielding effectiveness of the former is better than that of the latter in a double-wall shielding structures under the condition of identical area density and configuration. |
