The Experimental & Numerical Simulation of the Standoff Effect to Penetration Properties

In order to study the relationship between standoff distance and the penetration depth,penetration process of the cylinder-cone shaped charge without shell is numerically simulated.The jet penetration to the 45 steel target at different standoff is studied,compared with the experimental results.It is indicated that numerical simulation results agree with experimental results well.The ratio of effective standoff to charge diameter for the cylinder-cone shaped charge is about 1.4～1.8,while the maximum penetration depth is approximately 4.6 times of the charge diameter.
