New rock material definition strategy for FEM simulation of the rock

It was tentatively deduced that the grinding-crushing process and plastic hardening of rock in different parts may strongly influence the simulation results. In order to prove the deduction and build a reasonable numerical model, four comparative simulations were carried out with different material definition strategies of the rock specimen.
