“…The results show that when the mass of reactive material liner and aluminum liner is equal, the reactive material liner can effectively form a jet, and its morphology is similar to the aluminum jet. Furthermore, a series of experiments for the forming behavior of the reactive material jets are studied [12,13]. The experimental results show that the reactive material liner can form a reactive jet with excellent performance.…”

The density evolution behaviour and distribution characteristics of the explosively formed reactive material jet were studied based on the SPH algorithm. Numerical simulations show that the reactive material jet has obvious expansion phenomenon under the shaped charge effect. Especially, the expansion and divergence of the jet head are obvious. In general, the density deficit occurs in the whole reactive material jet, and the density increases from the jet head to the tail. Compared with the initial density of the reactive liner material, the density of jet head decreases by about 30%. In addition, the effect laws of the reactive liner thickness, the liner cone angle, and the type of explosive on the jet density distribution were investigated. With increasing of the reactive liner thickness, increasing of the liner cone angle, and decreasing of the explosive detonation pressure, the proportion of the high-density area on the reactive jet and the average density of the jet head increase.
