This paper using LS-DYNA finite element analysis program to model the damage process of oilcan steel plate under No.3 rock explosive load, analysing the effect of the mass and shape of explosive to steel plates extent of damage and shape of crevasse.

• 利用LS-DYNA有限元程序，模拟了油罐钢板在3(上标%23)岩石炸药爆炸载荷下的破坏过程，分析了炸药质量、药柱形状对钢板破坏程度和破口形状的影响。
