弹丸垂直侵彻钢筋混凝土介质的工程解析模型

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

在球形空腔膨胀模型的基础上,计入了弹丸直接与钢筋发生碰撞的侵彻阻力,建立了弹丸垂直侵彻钢筋混凝土介质的工程分析模型。与单一空腔膨胀模型和试验数据进行对比,表明了模型的有效性和实用性。并利用此模型分析了配筋直径及网眼尺寸对弹丸侵彻深度的影响。

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.
