NUMERICAL SIMULATIONS ON ROCK DAMAGE UNDER EXPLOSION LOADING
爆炸荷载下岩石损伤的数值模拟研究

Numerical simulations on rock damage under explosion loading are studied by use of the new rock dynamic damage model established. The rock damage evolution rules and the fragmentation process during ditching millisecond blasting are fairly delineated, which contribute to study the mechanism of millisecond blasting, the rock blasting theory and the engineering blasting design.
