Study on meso-fracture and energy evolution law of rock under sleeve fracturing

In order to reveal the micromechanics of rock failure mechanisms and energy transfer patterns under different confining pressures during sleeve fracturing, a PFC3D numerical model was established based on sleeve fracturing tests and expansive force measurement experiments. The discrete element metho...
