中文摘要：
模拟了炸药爆炸对金属结构的破坏,以LS-DYNA为仿真平台,分析了所应用的材料模型,比较了不同单元网格密度对计算结果的影响．对于平面应变问题,比较了采用二维和三维模型时在算法方面的区别,并对它们计算的结果进行了对比．与实测结果对比表明,用LS-DYNA可以有效模拟金属结构在爆炸荷载作用下的冲击响应．
英文摘要：
The metal structure damage under explosion of detonator is simulated by LS-DYNA. The material model applied is analyzed in detail. The difference between Euler and Lagrange algorithm is described. The influences of different meshing density on the precision of results are compared. In the plain strain problems, both two-dimensional and three-dimensional models are applicable, and their calculation results are compared. The comparison with the experimental results shows that the LS-DYNA can simulate the impa...
