Study on jet formation and penetration behaviour of shaped charge with reactive material composite liner

Abstract The shaped charge with reactive material composite liner could not only meet the requirement of after-effect damage behavior, but also achieve a deeper penetration capability. Based on platform AUTODYN-2D code, jet formation characteristics material-titanium and its behavior to multi-spaced plates were studied. Numerical simulations showed that increasing detonation pressure explosive, tip velocity capability increased, was subjected higher temperature rise within elements larger. In addition, influence standoff protective steel block thickness investigated. As increases from 0.5 CD 3.0 CD, capacity mass materials follow-in spaced decreased. With thickness, decreased gradually.
