中文摘要：
介绍了一种适用于侵彻计算的混凝土材料模型，通过所建的有限元程序对杆弹侵彻混凝土靶进行了数值模拟．正侵彻的计算结果和实验结果具有较好的一致性，能够模拟杆弹侵彻混凝土靶的成坑和损伤分布情况；对不同倾角和初速的斜侵彻进行了模拟计算．结果表明，该文方法和所建程序是合理的、有效的，为混凝土侵彻过程的数值分析提供了参考。
英文摘要：
A concrete material model for penetration computation was presented, and the ogivenoded rod projectile penetrating concrete target was simulated by a 3D finite element program. The results of normal impact are in good agreement with the experiments, and the development of crater and penetration hole were also obtained. Oblique penetrating of different incline angles and initial velocities are simulated and analyzed. The attained donclusions show that the method and the program are reasonable and effective, and it is a useful method for the numerical study of impact penetrations.
