Directional Cooling-Induced Fracturing: Directional Cooling Data Under True-Triaxial Stress State

Published by University of Wisconsin - Madison | Department of Energy | Catalog Last Checked: August 03, 2026 at 01:01 AM | Dataset Last Updated: July 09, 2024 at 04:24 PM
Data includes Directional Cooling-Induced Fracturing (DCIF) testing data using westerly granite blocks. This submission includes data from two samples of westerly granite, lab sample 7 and 8. Files contain stress, temperature and acoustic emission data acquired during polyaxial, laboratory testing of westerly granite blocks for each sample. FILES: .tradb -- files containing acoustic emission waveforms; sqlite3 database .pridb -- files containing basic acoustic emission information (no waveforms); sqlite3 database .geom -- geometry of the AE sensor network (ASCII)
