Abstract

The use of perforated plates as part of an armored plate set to protect people and equipment in front of the target plate has long been considered by researchers. For this purpose, the use of one perforated plate in front of the target plate has been considered so far and it has been found that using a perforated plate in a set of armored plates has several advantages. But this plate set will not be able to provide 100% ballistic protection. For this reason, the idea of using two perforated plates in front of the base plate has been proposed and in this research, the consequences of this kind of arrangement have been analyzed by performing experimental and numerical studies. Observations show that the use of two perforated plates in front of the base plate, although it increases their thickness and weight, at the same time, it improves the ballistic protection of the set of armored plates against the incoming projectile, especially in the weaknesses of using one perforated plate in front of the base plate. By comparing deformations obtained experimental experiments and numerical simulations performed using LS-DYNA software, a good convergence between the results has been observed.
