Aluminum foam is a lightweight material with high energy absorption capacity. In this study A Nonlinear three-dimensional hydrocode numerical simulation was carried out using autodyn-3d, which is an extensive code dealing with explosion problems. In this simulation, a high explosive material (comp B) is blasted against several concrete panels. The model was first validated using experimental tests carried out by Chengqing and has shown good results. Several numerical tests were carried out to study two parameters that affect the deflection of reinforced concrete panels. The parameters included are the thickness of concrete target and the thickness of steel plate. The results showed that increasing the thickness of the steel plate has an insignificant effect on the deflection of the reinforced concrete target while increasing the thickness of the concrete panel has a significant effect on the deflection of the concrete target.

Antipenetration performance of honeycomb shelter under two repeat projectile strikes is investigated via test and numerical simulation. Among them, there are two kinds of test targets: cylindrical honeycomb structure target and reinforced concrete target; a numerical simulation target is a honeycomb-structure target composed of hexagonal honeycomb unit, and the size of the target is the same as that of the honeycomb-structure target in test. The results show that the damage area of the honeycomb-structure target is smaller than that of the reinforced concrete target under projectile strikes with approximately the same velocity. The damage range of the honeycomb-structure target is limited within the hexagonal cell getting contact with projectile left other cells with no damage. During the two repeat projectile strikes, the first projectile will deflect to some extent just as single projectile strike. The deflection of the second projectile is larger and is related to the distance between the strike points of the two projectiles. The results show that honeycomb shelter performs good under two repeat projectile strikes.

In order to study the dynamic responses of a high-speed projectile striking into the steel-reinforced concrete target, a grid-net method has been developed in this article. The measuring system is composed of the grid nets fabricated by fine cables, light-emitting diode lamps, power supply systems, high-speed photography, and so on. Each grid net was pre-embedded along the rebar net. Multilayers of the grid nets were distributed with given space. The light-emitting diode lamp turns down when the cable is cut off. The status of the lamps is recorded by the high-speed photography. The basic idea is to trace the projectile by the on-off states of light-emitting diode lamps. In association with the high-speed photograph, the variation of the projectile velocity and the final depth of penetration could also be obtained. The depth of penetration value given by the grid measurement method was validated by the experimental result and the prediction of empirical formula and they show good agreement with each other.
