Rock-Breaking Mechanism of Special-shaped PDC Cutter in Heterogeneous Granite

In order to clarify the rock-breaking mechanism of special-shaped PDC cutter in the difficult-to-drill formations(e.g. granite), the finite element method was used to establish a mesoscopic heterogeneous granite model with different mineral components, and 10 kinds of rock-breaking models were estab...
