Abstract: To improve the penetration performance and distribution homogeneity of multi-explosively formed penetrators (MEFPs), the factors that affect their configuration, velocity, and distribution characteristics are studied using a three-dimensional LS-DYNA coupled hydro-code. Three different kinds of integral MEFPs are tested in experiments. The results show that the arc plane liner of uneven thickness is easier to form MEFPs with a large length to diameter ratio. Tantalum and copper MEFPs have good penetration performance due to a higher length to diameter value and kinetic energy. The arc bracket and the equidistant array pattern of the liners are beneficial for obtaining better distribution homogeneity of MEFPs.

Keywords: multi-explosively formed penetrators, penetration performance, distribution homogeneity.
