Summary of Stick-Slip Data

This series of stick-slip experiments adopts six experimental protocols. Normal force loading is stress-controlled and maintained constant after reaching preset values, while shear force loading is displacement-controlled.Under a normal force of 1.5 MPa, two shear schemes are implemented:Constant shear rates of 0.3 mm/min, 0.35 mm/min, 0.4 mm/min, 0.5 mm/min, 0.8 mm/min, 1 mm/min, 1.2 mm/min, 1.5 mm/min, 2 mm/min, 3 mm/min, 4 mm/min, 5 mm/min, 6 mm/min, 8 mm/min, and 10 mm/min, totaling 15 constant shear rates. Among these, shear rates of 0.3 mm/min, 0.5 mm/min, 1 mm/min, 2 mm/min, 4 mm/min, 6 mm/min, 10 mm/min, as well as 0.2 mm/min, underwent an additional set of acoustic emission monitoring tests.Alternate shear rates of 0.3/0.2 mm/min, 0.35/0.2 mm/min, 0.4/0.2 mm/min, 0.5/0.2 mm/min, 0.8/0.2 mm/min, 1/0.2 mm/min, 1.2/0.2 mm/min, 1.5/0.2 mm/min, 2/0.2 mm/min, 3/0.2 mm/min, 4/0.2 mm/min, 5/0.2 mm/min, 6/0.2 mm/min, 8/0.2 mm/min, and 10/0.2 mm/min, totaling 15 alternate shear rates. Among these, alternate shear rates of 0.3/0.2 mm/min, 0.5/0.2 mm/min, 1/0.2 mm/min, 1.5/0.2 mm/min, 2/0.2 mm/min, 4/0.2 mm/min, 6/0.2 mm/min, and 10/0.2 mm/min underwent an additional set of acoustic emission monitoring tests.Under normal forces of 3 MPa and 5 MPa, two shear schemes are also implemented:Constant shear rates of 0.3 mm/min, 0.8 mm/min, 2 mm/min, 4 mm/min, 6 mm/min, and 10 mm/min, totaling 6 constant shear rates for each normal force.Alternate shear rates of 0.3/0.2 mm/min, 0.8/0.2 mm/min, 2/0.2 mm/min, 4/0.2 mm/min, 6/0.2 mm/min, and 10/0.2 mm/min, totaling 6 alternate shear rates for each normal force.
