| Abstract: | Based on multi-material arbitrary Lagrangian-Eulerian coupling algorithm(ALE),a finite element model is presented for the simulation of the breaking processes of rocks under pulse water jet,taking into account the difference of jet velocity.The effect of jet velocity on the efficiency of rock breaking is investigated,and the favorate velocity of jet is suggested.The result is significant for people to understand the mechanism of rock breaking under pulse water jet and to develop the corresponding technologi... |
