| Abstract | ||||
| Protective layers of fortified structures are considered key points in resisting missiles. Most of these protective layers are made from plain concrete. Due to the progressive development of military destructive weapons such as hyper-velocity missiles, plain concrete protective layers are not sufficient to resist the effect of hyper-velocity objects. So it is essential to have a new generation of protective layers to able to resist this kind of weapons. The objective of this paper is to enhance the protective layer material through designing a special concrete mixture with high reliability to resist the penetration of hyper-velocity object. Ferrocement technique is used to enhance the concrete panels’ penetration resistance. A parametric study is performed on the effect of changing number of the steel wire mesh layers inside the concrete panels on its penetration resistance. The study in this paper is based on the finite element model verification conducted by M.E. Mohamed et al. using AUTODYN-3D on “Numerical Simulation of Projectile Penetration in Reinforced Concrete Panels” [1]. Also, plain concrete and ferrocement panels’ penetration resistance was studied under the effect of hypervelocity objects. This Hyper-velocity projectile was presented in experimental work conducted by Dawson [2]. The main findings of this paper were that there is an enhancement in the penetration resistance for ferrocement panels rather than plain concrete once. Also increasing of steel layers mesh number have slight influence on the penetration resistance of the ferrocement panels. | ||||
