Shaped Charge Jet

Shocking temperature rise of the shaped charge with porous liner before collapse was calculated based on the Herrman equation of state. Shaped charges with 36mm charge diameter were used to fire at the 603 armor steel target, the penetration-standoff curves(P-S) of the shaped charge liner with 88.6% and 90.3%T.D were measured and compared. It is shown that proper porosity is helpful to lengthen the jet break up time and penetration depth，which is of significance for the application of porous liner.

In this paper, the effects of the use of various aluminium materials as liner material in shaped charges for the perforation of concrete slabs are examined with numerical simulations. Using AUTODYN-2D software, formation of the shaped charge jets for seven different aluminium materials are modelled first and then these jets are directed to 35 MPa compressive strength concrete slabs. Those analyses are performed for a constant liner thickness which corresponds to 8% of the shaped charge diameter. Furthermore, the effect of standoff on the penetration of concrete slabs is examined by using shaped charges with the same geometry and liner material (7075-T6). The cone angle of the shaped charge is taken as 100°.
