| Abstract: | A method of numerical simulation of underground explosion process of cylindric charges is used to study some dynamic problems by taking advantage of Ls-dyna3D, such as the formation and development of cavitation and the motion law of explosion cavitation, in accordance with cylindric charges explosion in semi-infinite soil medium. The results of numerical simulation are compared to the experimental ones. The results of numerical simulation and simulative calculation are analysed. |
