  A numerical study of the disc cutter behaviour while cutting hard rocks

  Abstract: The present study investigates the structural behavior of the disc cutter as well as the local behavior, namely stress-strain evolution within the rolling disc cutter while cutting a hard rock block, which is directly related to the disc cutter degradation. The investigation has been carried out using a 3D numerical model in the commercial Finite Element code LS-DYNA. The influence of various...

  Modeling of the rock cutting process in hard rock applications

  Abstract: 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...
