| 摘 要： | 采用嵌入高压状态方程的Johnson-Cook混凝土本构模型,利用有限元程序MSC.Dytran,对动能弹以200～1000m/s的速度侵彻混凝土靶板进行数值计算,得到弹体的速度曲线、加速度曲线及不同弹体初速度下的最大侵彻深度；并结合弹体几何相似准则,给出弹体无量纲初速度和无量纲最大侵彻深度间的关系.

| Abstract: | In this paper,the Johnson-Cook constitutive model with high-pressure equation of state for concrete is inserted into finite element MSC.Dytran,with it simulations on penetration of a projectile into concrete targets are completed at velocities of 360-1 058m/s.The penetration velocity,the penetration acceleration and the final penetration depths are obtained.According to the body geometric similarity,the relationship between dimensionless velocity and dimensionless penetration depth is given. |
