Abstract
Resistance to penetration by high velocity projectiles through concrete target is an essential design parameter for fortification structures. Due to the expensive costs of field test experiments, numerical modeling is considered one of the most efficient procedures to predict the response of concrete panels under the effect of impact loads. The change in strain rate influences the material behavior. Studying this behavior needs experimental test. In this study, the experimental work is conducted to record the penetration depth through the concrete panels using the bullet at the industry. Two different panels are tested. Each panel has a different arrangement in the ferrocement layers. The finite element analysis (FEA) is
used to model the concrete panels subjected to the penetration of the bullet. The results obtained by the FEA are compared with those obtained by the experimental work to verify the proposed finite element model. Different initial velocities of the projectile are set to study the response of the target. The penetration depth and the strain energy are compared for each panel. The difference between the penetration depth and the strain energy, can describe the influence of the strain rate on the target behavior. The performance of the concrete panel reinforced by the ferrocement is
improved to reduce the penetration of the bullet.
