Abstract
In order to obtain the MEFP with smaller divergence angle for the apply in the destruction of unexploded ordnance, LS-DYNA numerical simulation software was used to simulate the formation process and motion state of the projectile formed by the integrated MEFP warhead. The influence of the parameters of the liner (thickness, radius of curvature) and the initiation mode (single and multi-point initiation) on the formation characteristics of MEFP were studied. After the optimization design of warhead, the simulation model of MEFP interact with shell-covered cylindrical charge was established to estimate the damage power. The optimized MEFP has small divergence angle and can detonate the shell charge with a thickness of 10 mm.
