Abstract

Recently the use of Reactive Shaped Charges with Bimetallic Liners are taken into consideration to increase destruction quality in water environments. In this research, according to the results of a series of valid experimental results, the analysis of a Reactive Shaped Charge with a Bimetallic Liner made of copper-aluminum liner has been numerically verified. In this verification, a suggested theory for the cutoff velocity of Bimetallic Liners has been used to calculate the cutoff velocity. The amount of penetration depth using a numerical solution is in good agreement with the experimental value. These results have been compared with the values obtained from the analytical solution. Finally, the behavior of the shaped charge with Bimetallic Liner has been compared with a single metallic liner using the same target geometry in both and it has been shown that the overall penetration quality such as depth, diameter and the profile of Reactive Shaped Charge with a Bimetallic Liner was found to be better than the single metal liner.
