  Modeling of the rock cutting process in hard rock applications

  In the present study, a FE model accounting for the rock breaking process has been proposed in the commercial FE code LS-DYNA to simulate the rock cutting process for hard rock applications. A sensitivity study has been carried out to understand the influence of different numerical discretization parameters on the performance of the model, namely the mesh size and element type. An improved analytical model has been proposed in order to account for the nonuniform pressure distribution in the tool/rock contact zone together with a calibration procedure for the FE model combining theoretical and experimental results in terms of the cutting force-cutter displacement evolution. It is shown that the calibrated FE model can provide a reasonable prediction of the cutting force
