    Abstract
  • A kind of charge structure for multiple explosive forming projectile is put forward to improve the directional destruction effect on targets. The plane wave produced by shock initiation and initiation styles effecting on damage ability are simulated by LS-DYNA and tested. Results show that MEFP charge with VESF initiation has many advantages, such as higher velocity EFP, higher directionality and being easy to initiate charges of large ratio of height to diameter.
