Abstract

Abstract

In this study, the resistance model of rigid flat-nosed projectile penetrating reinforced concrete target was established, in which the failure mode of reinforcing bar in reinforced concrete was simplified as bending shear failure on the foundation of plain concrete penetration theory. The calculation results of penetration depth agreed well with Young's formula. The results indicated that the model established in this study could reasonably predict the penetration depth. The results show that the penetration depth of the projectile impacting the mesh center is maximum when the ratio of the projectile diameter to the mesh size is less than 1, and the most unfavorable target position depends on the ratio when it exceeds 1. In view of protection, an engineering calculation formula of penetration depth was proposed under the most unfavorable working condition of.
