以下为句子列表:
英文: Abstract: Incompatible element NH11 and hybrid stress element 18β were employed to analyze rock burst occurring in coal face 9108 of Sanhejian Coal Mine.Compared with the results from ANSYS,the two optimized FEMs can execute more accurate numerical simula
中文: 文摘:利用优化非协调元和杂交元分析了三河尖矿冲击矿压,并与ANSYS程序的计算结果进行了比较.认为优化有限元在冲击矿压乃至岩石材料的数值模拟中能给出更为精确的结果,也可减小大型计算中由于人力、机时所限粗分网格产生的误差.分析中,采用了广义平均应力率准则来判断冲击点位置和冲击时刻,所得结论与实际情况吻合.
