N2 - In order to study the influence of the layers on multi-layered liner shaped charge (MLSC), the jet forming characteristics of the MLSC consisting of different metal materials were investigated. Two-layered and three-layered liner shaped charge have been designed with different combinations of material and thickness of the liners. A single-layered Cu liner with the same structure is also simulated as a baseline. The simulation results show that the pressure on the inner cover on the MLSC structure can be increased by increasing layers of the MLSC. As the pressure increases, the jet velocity of the MLSC also increases compared to that of the single-layered Cu liner, with the three-layered liner having the largest velocity. When the inner liner thickness of the three-layer liner is 0.2 mm, the jet formed by the MLSC has the highest head speed.
