    Abstract
  • The three-dimensional nonlinear dynamics of particle impacting breaking rock is simulated with LS-DYNA3D. The energy conversion curves and the process of rock breaking under steel particle are obtained, and the mechanism of rock breaking is also analyzed. The simulation results agree with the experimental observations basically. Therefore, this simulation is feasible and can be used as a good reference for optimizing hydraulic parameter for oil well drilling.
