Experiments include velocity-stepping and fluid pressure stepping experiments.

Non-linear acoustic data acquired via Verasonics systems connected to PZTs inside the pressure vessel give the timeshift, amplitude and RMS amplitude of the passing P-wave.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://gdr.openei.org/files/1400/comb_data_Test07.mat", "description": "Velocity step test on 30 degree saw-cut Westerly Granite at room temperature.
