Numerical Simulation of Forming Process of Multi-effect MEFP
In order to expand application of EFP warhead in new intelligent ammunition, a multi-effect MEFP charge structure was designed which could form a main EFP and 16 circumferential auxiliary EFP. Numerical simulations using AUTODYN software were carried out to research influence of the parameters of li...

| description | In order to expand application of EFP warhead in new intelligent ammunition, a multi-effect MEFP charge structure was designed which could form a main EFP and 16 circumferential auxiliary EFP. Numerical simulations using AUTODYN software were carried out to research influence of the parameters of liner on formation of this kind of MEFP warhead. The results show that both curvature radius and thickness of the auxiliary liner have a great influence on shape and velocity of the auxiliary EFP, while radial dispersion of the auxiliary EFP decreases obviously with increase of the auxiliary liner angle. When the parameters of liner are reasonable, the kinetic energy of the auxiliary EFP is larger, the shape is close to spherical, and the damage effectiveness is better. |
