The experiments of extended penetrator oblique penetration into finite target are carried out.

The variation of kinetic energy with time was got for extended penetrator and baseline rod respectively.

The extended penetrator penetrating single layer and two-layer spaced targets with attack angle were simulated with LS-DYNA3D,which were compared to that of the baseline rod with the same mass and outer radius.

Numerical Simulation of Formation Process of Jetting Projectile Charge by Flyer Initiation;

In order to analyze the influence of the detonation of the explosive to the penetration capability of the rod penetrator,the penetration process at different impact angle into plate covered by sandwich explosive are simulated by 3D finite element code(LS-DYNA),which are compared with the corresponding cases without explosive in the middle of two plates.

Different configuration of shaped charge can form different penetrators, such as jet toattack decorous armor, Jetting Projectile Charge (JPC) to deal with decorous armor at furtherranger, or Explosively Formed Projectile (EFP) to invade light armor.

By using LS-DYNA finite element hydrocode,the effects of liner\'s cone angel,wall thickness and wall thickness variation on the penetrator formation of shaped charge conical liners were investigated under direct and inverse direction annular initiations.

In order to study the effect of stern charge configuration on the performances of penetrators,the formation of penetrators is simulated by LS-DYNA software.
