| Abstract: | In order to study the physical mechanism of explosion field in concrete,a code MMIC-3D is proposed based on the 3D Youngs' interface reconstruction algorithm.The formation and development process of the cavity and the law of bulge motion during the explosion in semi-infinite concrete are simulated.The three-dimensional numerical results of the explosion field in the semi-infinite concrete medium are obtained.The results showed that the computational data agree with the experimental phenomena and the physica... |
