摘要
针对高速撞击条件下混凝土的Johnson Cook计算模型 ,以混凝土的静态抗压强度为基础 ,利用美国ACI提出的混凝土强度计算的一些经验公式 ,同时通过对计算数据的分析 ,最后给出一种简易的确定混凝土损伤模型参数的方法 ,并将数据计算结果和已有文献的实验数据进行了比较 .
Based on Johnson-Cook model for concrete under high-speed impact, and static compress strength, and the analysis of corresponding computational data, a kid of method, in which some empiric relations, presented by ACI, and used to compute concrete strength, were employed. Finally, the comparison between numerical results and experimental data from corresponding references was done.
