Abstract

Abstract

Non-linear dynamical finite element software AUTODYN was used to simulate the shock initiation of steel-covered charge impacted by high-velocity fragments. The interlayer effect was studied based on the pressure history of initiation when different materials and thickness interlayers were used. The results show that the interlayer material is an important factor affecting pressure history and run-to-detonation of explosives, the thickness of interlayer has the same effects. The initiation of explosives can be effectively prevented with changing the thickness and material of the interlayer.
