The object of research is the processes pulse explosive loading in an explicit formulation for simulation complex nonlinear dynamics solids, gases, and their interactions. One most problematic areas modern studies dynamic loads materials using a numerical analysis that such usually do not take into account characteristic transition stationary deformation zone loaded material to unsteady one fro...

Abstract The AUTODYN-2D simulation software was used to study the jet formation of single-cone and biconical shaped charge liner damage influence on RHA target. numerical results show that compared with typical structure, head formed by is faster has better penetration performance On this basis, standoff, cone angle line thickness characteristics target under studied. when standoff increases fr...

Abstract The UAV-Brone Kinetic Kill Vehicle (KKV) can effectively enhance the defense capability at low and medium altitude by intercepting missiles other aircrafts in a reverse orbit manner. This paper mainly studies interception damage effectiveness of typical KKV energy interceptors to cluster warheads. Based on equivalent principle “the main material remains unchanged, mass size unchanged”,...

Overpressure is an important metric of the destructive effect shock wave produced by high explosion. Investigating overpressure on surface essential way for evaluating power explosive device. This study has implications quantitative analyses establishing relationship between parameters reflected using numerical simulation software AUTODYN with different TNT charge mass. The research indicates t...

Abstract A thermodynamic model capable of predicting the change in internal energy, work done, and thermal energy required during aluminum-stainless steel explosive cladding is presented. The mathematical instrumental determining temperature pressure developed at interface, which characterizes interface microstructure, compared with numerical simulation. Numerical simulation implemented by Smoo...

Abstract In order to discuss the effect of different outer liner material on performance double cylinder-cone shaped charge, nonlinear dynamics software Autodyn-2D was used carry out numerical simulation, and jet shape penetration steel target were analysed when copper, nickel, tungsten, tantalum as materials copper inner cover material. The result shows that head is formed by cylindrical part ...
