Research On Terminal Penetration-induced Initiation And Damage Effect Of Reactive Material Enhanced Penetrator

Reactive material and its application in warhead is one trend of efficient damage researchfield，attracting high attention and vigorous development by weapons and ammunitionresearch institutions all around the world，due its unique penetration-induced initiation anddamage effect. The reactive material enhanced penetrator is one of the most valuableapplication of reactive material to enhance the lethality of the semi-piercing projectile.Through theoretical analysis and numerical simulations， the terminalpenetration-induced initiation and damage effect of reactive material enhancedpenetrator was studied. Here focus on the dynamic analysis of penetrator/plateinteraction, an analytical model for penetration-induced initiation behavior of thereactive material enhanced penetrator is developed，analyzing the influence of thepenetrator parameters，shell materials and impact conditions on its terminal effects. Theprocess of reactive material enhanced penetrator penetrating metal target was simulatedby using AUTODYN-3D code to investigate the mechanical behavior. A preliminaryregulation of the influence factors such as length/diameter ratio，impact velocity andmaterial of target，etc. in the mechanical behavior of penetration were obtained bysummarizing and analyzing the simulation results. The penetration-induced initiationand its combined damage effects，produced by the reactive material enhanced penetratoragainst multi-plate target was also simulated. The influences of impact velocity andplate material in damage effects were obtained by analyzing the penetration process.The research achievements have significant reference value on the design，development，weapon application and terminal execution evaluation of reactive materialenhanced penetrator.
