摘要
运用LS-DYNA软件的Lagrange、ALE和SPH三种不同算法对炸药在钢筋混凝土板表面触爆进行了数值模拟,3种算法都模拟了表面触爆下炸药爆轰及混凝土板破坏的全过程。通过实际算例从模型建立、计算结果和计算时间3个方面对比分析了3种不同算法的优缺点,从而为爆炸效应数值模拟方法上提供一些建议和参考。
Using Lagrange、ALE and SPH of the LS-DYNA software,numerical simulation has been conducted for reinforced concrete slab under contact explosion.Three different methods simulate the whole process of detonation and damage of slab.With the detail example,three different methods′ merits and drawbacks are analyzed in the aspect of model、simulation results and computing time.This will offer some suggestions and references for simulation method on explosion effect.
