Abstract

Multiple explosively formed projectiles (MEFP) can effectively raise utilization and hitting probability of explosive. The process of penetrating double-layer nonseptate steel targets with grooved MEFP was studied based on ANSYS/LS-DYNA in this paper. The results of numerical calculation was got by creating 3D model, different state equations and constitutive equations were selected by different materials, meshing was conducted by solid element and shell element. Calculated results show that penetration process should pass through three stages: spud-in stage, unite penetration stage and throughout stage. The simulation results are consistent with the experimental results.

Key words： ANSYS/LS-DYNA; numerical calculation; multiple explosively formed projectile (MEFP); penetration mechanics
