Abstract: | Spaced armor has a simple structure and is easily produced with low cost. Previous authors calculated how a jet penetrates spaced armor; but, this study provides both a theoretical calculation method describing the interaction of a jet with spaced armor and experimental data which agree well with the theoretical values. The effects of several factors were explored using LS‐DYNA such as the distance between the first plate and the second plate as well as layer thickness on the interaction between the jet and the target. A method for simulating the protection afforded by spaced armor and supporting the design of spaced armor is presented. |
