摘　　要：素混凝土侵彻效应研究对防护工程设计和钻地武器战斗部研究都具有重要意义。本文建立三维有限元模型进行卵形头部弹丸侵彻素混凝土数值模拟分析,结合Young公式和空腔膨胀理论在侵彻深度和侵彻过载等方面对素混凝土侵彻效应的数值模拟结果进行分析,对比结果显示数值模拟分析具有较好的可信度,丰富了素混凝土侵彻效应研究的方法和途径。It is important for the design and research of the defense engineering and earth-penetrating weapon warhead to study the penetration effect of plain concrete.This paper builds 3D finite element model to simulate the ogive-nose projectile penetration into plain concrete targets.Based on Young formula and cavity expansion theory,the comparative analysis of penetration effect is conducted between the numerical simulation and the empirical formula of experiment or theory formula about penetration depth and penetration deceleration,which shows the numerical simulation is highly reliable.So the study enriches the research way and method of the penetration into plain concrete targets.
