Abstract

Abstract

In this study, based on SPH and using AUTODYN-2D, we analyzed the hyper velocity penetration of tungsten rod into four types of layered shielding structures consisting of granite shielding layer, air/sand distribution layer and concrete structure layer, and obtained the structures' damage and energy distribution, with the following results achieved:(1) Although raising the striking velocity increased the damage of the shielding layer and the distributing layer, the penetration depth into the structure layer decreased within a certain velocity range; (2) The ratio of the energy conducted to the structure layer generally decreased with increasing of the striking velocity, and this could be attributed to the transverse propagation of the impact energy within the shielding layer and distributing layer; (3) Under certain conditions, addition of an air layer could reduce the penetration depth into the structure layer, the ratio and absolute value of the energy conducted to the structure layer.
