In this study, the protective capability of the water-filled cylindrical chamber against shaped charge ammunition is evaluated. The effects of the chamber parameters, such as the diameter, length, and sidewall thickness, on the penetration depth in the witness plate placed behind this chamber are investigated. The numerical FEM analyses that utilize 2D Axisymmetric Multi-Material Arbitrary Lagrangian Eulerian (ALE) method are conducted using LS-DYNA software. The stability and the particulation of the copper jet affect its penetration to steel targets. Using these analyses, the mechanism that causes the instability and the particulation of the jet while it passes through the water-filled chambers with different parameters is visually demonstrated and explained. Furthermore, tests are conducted using the critical chamber parameters that are obtained from the analyses to verify the results.
