| Abstract: | Based on the theory introduced by professor Qian Qihu in paper,a numerical simulation method calculating shock wave loading produced by air explosions, acting on underground defence structures, is given, which is useful in the dynamic finite element analysis of structures. With the use of this principle, the program used for shock wave loading generation is finished, so that the precision and efficiency of the dynamic finite element analysis of underground structures can be improved. |
