摘要
对比等效混凝土，采用二维拉格朗日弹塑性流体力学有限元程序LTZ-2D分析了骨料对混凝土爆炸毁伤效应的影响。通过对计算结果的对比分析，骨料对混凝土的爆炸毁伤区域影响不大，含骨料混凝土模型的作用主要显示在骨料对裂纹发展方向的影响。研究结果可以为相关问题的数值分析提供参考。
In this paper,comparing common assumptions of an even concrete target, we consider the influence of the aggregate on the damage of concrete under blast loading in numerical simulations. The code we used in this study is a 2-D Lagrangian elastic-plastic hydrodynamic finite one, named LTZ-2D. Numerical results show that differences of damage in even concrete targets and aggregate concrete targets are small;the aggregate has an effect on the expanding of cacks.
