摘要: 以侵彻深度(depthofpenetration,DOP)实验为基础,利用LS-DYNA 软件进行数值模拟,对钨合 金长杆弹侵彻45钢鉴证靶和约束AD95陶瓷复合靶进行了对比研究。通过数值模拟与实验结合的方法,得 到了AD95陶瓷的JH-2模型(Johnson-Holmquistceramicmaterialmodel)参数;深入分析了钨合金长杆弹侵 彻约束AD95陶瓷复合靶侵彻响应过程。Abstract: DOP(depthofpenetration)testswereperformedtostudytheballisticpenetrationcharacteristicsofconfinedAD95ceramictargetsbytungstenlongrods.
