Laboratory data for characterizing acoustic emissions during differential stress-driven and pore-pressure-driven failure in granite

This dataset contains acoustic-emission (AE), ultrasonic-transmission, permeability, and hydromechanical measurements from triaxial laboratory experiments comparing differential stress-driven and pore-pressure-driven failure in saturated, thermally cracked Barre granite at 80 degree C. Cylindrical samples approximately 40 mm in diameter and 80 mm long were tested at confining pressures of 40 or 70 MPa and an initial pore pressure of 30 MPa using two loading paths: increasing differential stress at constant pore pressure and increasing pore pressure at constant differential stress. AE waveforms were recorded in triggered mode at 50 MS/s and continuously at 10 MS/s, producing more than 1,000 triggered and 10,000 continuous AEs per experiment. Supporting and derived products include stress, strain, pressure, permeability, active-ultrasonic measurements, waveform clusters based on dynamic time warping, AE source locations, spatial-temporal event patterns, and post-failure micro-CT fracture networks where available. The dataset supports investigation of rupture signatures under stress and fluid-driven loading and development of AE classification, geothermal seismic-monitoring, and adaptive traffic-light methods.
