NUMERICAL SIMULATION OF BOARD MEDIUM DESTRUCTION IN THE CLOSELY BLASTING ACTION |
| |
| Abstract: | In this thesis,a 3-dimensional numerical model of board medium is built with the help of LS-DYNA,and the simulation result about blasting process of the board medium destruction is analyzed on the basis of LS-DYNA970 solvers and st-processing.Through numerical simulation,two processes after the ex-plosion are objectively showed.One is about the transmission process of the shock wave through the earth,and the other is about the board when it receives a certain force from the shock wave.The thesis also made a further analysis about the board medium destruction in the blasting action.In this thesis,a 3-dimensional numerical model of board medium is built with the help of LS-DYNA,and the simulation result about blas-ting process of the board medium destruction is analyzed on the basis of LS-DYNA970 solvers and st-pro-cessing.Through numerical simulation,two processes after the explosion are objectively showed.One is a-bout the transmission process of the shock wave through the earth,and the other is about the board when it receives a certain force from the shock wave.The thesis also made a further analysis about the board medi-um destruction in the blasting action. |
