超高性能混凝土(Ultra High Performance Concrete，UHPC)是一种同时具备超高强度、超高韧性的新型防护材料，是结构抗冲击设计的理想材料。本文利用Φ35mm火炮对160MPa UHPC靶板开展了216~350m/s速度下的侵彻试验，试验表明，随着弹体速度的增加，侵彻深度与开坑直径皆有明显增加。UHPC材料模型采用LS-DYNA软件中的MAT_RHT模型，为了验证材料模型的有效性，采用霍普金森压杆（SHPB）试验结果对三维有限元模型进行了验证。利用验证过的本构模型，使用LS-DYNA有限元软件模拟UHPC的侵彻过程，对弹体侵彻深度、弹坑直径等方面的数值计算结果与实验结果进行了比较。在此基础上，参数化分析了UHPC抗压强度、弹体质量、侵彻速度、弹径、弹头形状系数（CRH）对UHPC侵彻深度的影响，并据此推导出UHPC侵彻深度计算公式。
Ultra High Performance Concrete (UHPC) is a new type of protective material with both ultra-high strength and ultra-high toughness can be adopted as an ideal material in the impact resistant design of structures. In this paper, the impact resistance of 160MPa UHPC was investigated experimentally by conducting the high-speed projectile penetration tests which launched by the 30mm-diameter, smooth-bore powder gun at the striking velocities 216 m/s and 350 m/s. The test results show that with the increase of projectile velocity, the penetration depth and crater diameter increase obviously. The MAT_RHT is implemented into finite element package LS-DYNA for UHPC. In order to verify the accuracy of the material model, split Hopkinson pressure bar (SHPB) testing results are used to validate 3D finite element material model. With the validated numerical model of UHPC, Numerical studies are conducted to simulate the projectile penetration process into UHPC targets with the assistance of a computer program LS-DYNA. The numerical results in terms of the depth of penetration and crater diameter are compared with the experimental results. In addition, parametric studies are conducted to investigate effects of UHPC compressive strength, projectile mass, projectile striking velocity, projectile diameter and projectile caliber-radius-head (CRH) ratio on the depth of penetration of UHPC targets. Moreover, an empirical formula to predict the depth of penetration is derived according to the simulated data.
