Abstract

The 3D computational simulation results of the jet formation in shaped charge under eccentric initiation were presented. These calculations were performed using finite element code LS-DYNA, and compared with X-Ray measurement. For this shaped charge configuration, the effect of 1mm off-center initiation on jet formation is very low, the lateral drift velocity increases drastically with 2mm off-axis initiation, and the shaped charge jet breaks severally into particles when the eccentric value increases.

Key words： mechanics of explosion; shaped charge jet; eccentric initiation; jet formation
