| 摘 要： | 为研究壳体对混凝土毁伤效果的影响规律,运用AUTODYN-2D对裸装药和不同厚度钢壳装药爆炸毁伤混凝土进行了数值模拟,结果表明,裸装药爆炸毁伤混凝土后的有效破坏区半径R2值比薄壳体时的小,但比较厚钢壳体时的大,这与试验结果吻合.壳体的存在对于最终毁伤效果的影响,视钢壳体的厚度而定.

| Abstract: | In order to explore the laws of shell charge explosion and damage in concretes,the numerical simulations were carried out by using the AUTODYN-2D software about the shell charge and no shell charge explosive damage in conretes,and the results indicate:the effective destructive radius R2 under no-shell charge is smaller than the value under more thin shell charge,but it is bigger than the value under more thick shell charge.This conclusion basically tallies with the experiments.The steel shell′s influence on the lastest damage effect is decided by its thickness. |
