Abstract
There are few research papers of liner shaped charge (LSC). In this time simplified LSC was made from an explosive and vertically-folded copper plate. In order to confirm a performance of the simplified LSC, steel cutting experiments were conducted by changing distance from the simplified LSC to target steel. Numerical analysis was also conducted by using Ls-dyna. Penetration depth was measured after experiments. Collision velocity of copper was calculated by using Gurnney equation. Numerical simulation model was made by SPH, because large deformation was occurred during collision of copper and steel penetration process. Results from numerical analysis were good correspondence with experimental results. Details are reported on this paper.
