| 摘 要： | 本次计算的目的是为了模拟岩石质材料在爆炸情况下的损伤断裂,最终的结果是得到裂纹的发展情况。采用的工具是国际通用的大型有限元分析软件ABAQUS。ABAQUS在非线性、爆炸模拟方面具有强大的功能1,2],并且在ABAQUS的计算实例中给出了一些相关的爆炸模拟例子3,4],所以采用ABAQUS作为这次运算的工具是足够而充分的,最终的数值结果将与ABAQUS自带的爆炸计算实例进行对比分析来确定本次计算的合理性。

| Abstract: | The purpose of this calculation is to simulate the actual failure and breakage process of rock material in conditions of explosion and the ultimate result is to learn the trend of crack development.The tool is general nonlinear finite element analysis program-ABAQUS,which has powerful functions in nonlinear and simulation of explosion.Besides,some examples on explosion simulation are given in ABAQUS examples,so the use of this program is quite reasonable.The numerical results will be compared with the examp... |
