Numerical simulation explores rock-breaking and thermal characteristics in deep hard formations, suggesting effective designs for PDC bits.

The study aims to enhance rock-breaking efficiency and thermal performance of PDC cutters in hard formations.
Developed a finite element model of cutter-granite interaction based on elastoplastic mechanics.
Conducted uniaxial compression tests to validate rock constitutive parameters.
Analyzed cutter shape, back rake angle, and depth of cut effects on drilling efficiency.
Chisel cutter reduces cutting force by 13.4% and axial penetration reaction force by 22%.
The rate of penetration increases by 19.7% with the chisel cutter, while average torque decreases by 11.34%.
Thermal analysis shows chisel cutter maintains lower and more stable cutter-face temperatures.

Wu et al. (2026) studied this question.
