摘要
在球型空腔膨胀模型的基础上,计入了与弹丸直接发生碰撞的网筋的侵彻阻力,建立了弹丸垂直侵彻钢筋混凝土介质的工程模型。与单一空腔膨胀模型和试验数据进行了对比,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 spherically cavity-expansion model, counting with the resistant force of rebar, a engineering model for ogival nose projectile penetrated normally into semi-infinite reinforced-concrete targets are developed. The model predicated depths of pentration are in reasonable agreement with the test data. Then the effect of the radius of rebar and the size of rebar square are calculated and analysised.
