Abstract

BLU-113 is earth penetrator warhead commonly used. It has been simulated by using LS-DYNA finite-element software to analyze damage effectiveness of BLU-113, which BLU-113 attacks underground protective works under different deepness from 10 to 22 m. In the simulation, shotcrete layers, anchor-hold rocks and loose rocks are taken into account. The penetration process and explosive process of BLU-113 both are simulated. The calculating results reveal that co-damage effectiveness of penetration and explosion can´t be ignored in the study on earth penetrator weapon. And we may pay attention to BLU-113, because its damage effectiveness is very remarkable in the simulation.
