Micro Abstract:
This study presents computational simulation of rock cutting process using disc cutters, a typical process involved in mechanized rock excavation works. Peridynamics, a nonlocal continuum formulation, is used to model the LCM (linear cutting machine) test of rock cutting with a single TBM (tunnel boring machine) disc cutter. The presented numerical model enables the investigation of different cutting forces as well as of the stress and pressure distribution during the tool-rock interaction.
