Title Application and study of energetic and active material in the field of arms and ammunition
Abstract Energetic and active material liners technology is currently one of the hot research direction in the field of high efficient mutilate。 The effective damage to the target is due to the joint action of the jet penetrate damage and the releasing of active material’s chemical energy implosion by energetic and active material shaped charge, which is different from the commonly used shaped charge made by copper。
In this paper, there is a study about the damage effect problem of energetic and active material liners shaped charge by the method of theoretical analysis, numerical simulation and test。 According to the steel target, the analysis model of jet penetration and damage effect is established。 And the influences of cone angle and thickness of energetic and active material liners, blasting height on the damage effects is obtained by LS - DYNA numerical simulation。 The damage effect data of energetic and active material liners to steel target is also obtained by experiment。 Basing on the data, structural parameters of energetic and active material liners is optimized。 This paper would be a helpful reference to the design of shaped charge and the evaluation of the power of the energetic and active material liners。
Keywords Energetic and active material liners Shaped charge Steel target Damage effect Damage assessment
