• Shaped charges are used widely to penetrate into targets. The destruction level of them is measured by the depth of penetration profile and the diameter of the penetration profile crater. Changing the liner or duplicate its materials affects the rate of destruction (destruction level). It was reported that copper liner results in greater penetration profile depth and aluminum liner results in a larger crater diameter. In this research, first, the penetration profile of a copper liner shaped charge is theoretically and numerically analyzed using Autodyn software and compared to experimental ones which shows an acceptable agreement. Then, using the same process, the numerical solution of aluminum, nickel and bimetallic copper–aluminum and copper–nickel liners is performed. Comparing the experimental and numerical results, it can be calculated that the copper–aluminum liners have a good and proper penetration profile depth and crater diameter. The results are presented, discussed and commented upon.
