炸药输出能量在鉴定块中衰变过程的数值模拟

The numerical simulation on explosive energy output during the process of decay in a certain block of steel

应用ANSYS建立实验所采用的钢凹实验物理模型,通过LS-DYNA3D有限元分析程序,对钢鉴定块上炸药作用时炸坑深度进行数值模拟。结果表明,钢凹值随着压药密度的增加而增加。

Steel dent experiment physical model was adopted in the experiment which was based on ANSYS. The numerical simulation was conducted through LS-DYNA3D finite element analysis to record the eorrespongding depth of bombing pit caused by explosive which had been placed on the certain block of the steel. Result showed that the steel dent value went up as the explosive density increased.
