Numerical Simulations of SFRC Projectile Penetrating into Limestone Using FEM/SPH Coupling Method

Abstract:

The method of using efficient inert projectile with highly efficient propulsion has great potential for the rapid and efficient excavation of rocks and ore in both surface and underground. In this paper, a series of numerical experiments were performed to simulate rock fragmentation resulted from steel fiber reinforced concrete (SFRC) projectile by using hydrodynamic finite element code AUTODYN. The fully coupled method was been adopted, in which the limestone, molded using Lagrangian mesh, is coupled to SFRC projectile molded using smoothed particle hydrodynamics (SPH) method. The numerical model was verified by comparing the simulation results with the field experiment data. Furthermore, the effect factors of geometric parameters of SFRC projectile and fibers content on the muck production were also discussed. The results of this study suggest that numerical simulation could be substituted for field experiment used for performance assessment of SFRC projectile.
