An engineering analytical model for projectiles to penetrate normally into semi-infinite reinforced concrete targets

Ouyang Chun, Guozhi Zhao

Open publisher page 4 citations

Abstract

Based on the spherical cavity expansion model, and taking the resistant force of rebar into account, an engineering analytical model for ogival nose projectiles to penetrate normally into semi-infinite reinforced concrete targets has been developed in this paper. The model predicated depth of penetration is in reasonable agreement with the test data when compared with other models. The effects of rebar radius and grating size on the penetration depth are calculated and analysised.
