Experimental Studies on the Penetration into Concrete by the Shaped Charge Jets

Concrete penetration effects of Shaped-Charge are investigated by experimental method,and a wide variety of experiments were conducted on various standoff.The experiments result indicated that the larger standoff used.the lar- ger penetration depth and the smaller hole were obtained.Increasing the standoff is useful to the penetration depth,but too larger standoff can make penetration depth reduced because jet was fragmented.Detailed analysis and discussion of the experimental results is conducted at last and it is very valuable for the design of MWS.
