我想模拟炸药药柱在传爆药柱作用下,被冲击起爆过程。模型如下(准二维轴对称模型)
被发炸药(part1)及传爆药(part2)材料状态方程如下:
*MAT_NULL
1 1.8420000 0.0000000 0.0000000 0.0000000 0.0000000 0.0000000 0.0000000
*EOS_JWL
1 69.690000 -1.727000 7.8000000 3.9000000 0.8578000 0.1020000 1.0000000
*EOS_JWL
1 8.5240000 0.1802000 4.5500000 1.3000000 0.3800000 0.1020000 1.0000000
*EOS_ignition_and_growth_of_reaction_in_he
1,0.0,0.0,0.0,0.0,0.667,0.0,0.0

0.111,0.667,0.0,0.0,20,0.0,0.0,0.0

*MAT_HIGH_EXPLOSIVE_BURN
2,1.6500000,0.7360000,0.2500000,0.0000E+00
*EOS_JWL
2,5.3177,0.08933,4.6000000,1.05000000,0.3300000,8.0000E-02,1.0000000
炸药均采用ALE算法
*SECTION_SOLID_ALE
1,11
*SECTION_SOLID_ALE
2,11
*CONTROL_ALE
2 1 2 -1.0
*ALE_MULTI-MATERIAL_GROUP
1 1
2 1
在传爆药柱上设置起爆点。运行结果传宝药起爆,而被发药柱未被起爆。
请教高手!不甚感谢! |
