Numerical simulation of explosion process of a precise detonator
Kaida Dai, Kunihisa Katsuyama, Jun Yang, and Pengwan Chen


For analyzing detonation process of the concave-bottomed and flat-bottomed precise detonators, numerical simulations of detonators were carried out by using the nonlinear finite element code LS-DYNA. The simulation results of two type detonators are compared with each other. The expansion of detonation product is reproduced. It is consistent with results taken by the high-speed camera. The results can provide a base for further study, such as rock blasting etc.
