集团装药多层介质中爆炸作用数值模拟

Numerical Simulation of Blast Effects for Group Charge in Multi-layer Medium

在试验研究基础上,采用LS-DYNA非线性有限元分析程序,运用ALE算法,对装药在不同机场道面不同炸深条件下的爆炸过程进行了数值模拟研究,其结果与试验数据吻合得较好,为进一步研究道面厚度对爆破效应影响打下了基础。

Basing on the research of experiments, blast effects for group charge in different multi-layer medium at different depths was numerical simulated by using LS-DYNA nonlinear finite element analytical program with ALE arithmetic. The result of the simulation was well tallied with the date of experiments. It can be a good foundation for further research of explosive effects in different thickness of concrete in the future.
