| Content Summary | Two types of numerical models, namely a continuum and a micromechanical discrete element model, are employed for the theoretical study of rock cutting measurements by a new portable rotary microdrilling tool. Our objectives are: (a) to gain insight in the cutting mechanism of granular cohesive-frictional rocks, and (b) to examine the comparability of numerical model predictions with experimental results. In the first type of model, a plane strain continuum calculation is done with a non-hardening, elastic-plastic, Mohr-Coulomb material. In the second type of numerical model, distinct element calculations are done on a simulated plane strain sample of 540 discs. In both models measurements are made of components of traction applied to the cutting tool and compared with measurements taken with the acquisition system of the portable microdrilling tool during specially designed tests on Dionysos marble. | en |
