Item Scratch test results for Alabama marble(2022-07-18) Zhang, He; Le, Jia-Liang; Detournay, Emmanuel; detou001@umn.edu; Detournay, Emmanuel; Dr. Emmanuel DetournayThis dataset contains cutting force signals, videos of rock cutting processes, particle size distribution from sieving analysis obtained from scratch tests conducted on Alabama marble at different depths of cut, which cover the rock failure in ductile, fragmentation and brittle regimes. The force signals and videos can be used to study the rock failure mechanism and energy scaling in the rock cutting process. The particle size distribution data explains the energy dissipation in rock cutting process and the scaling law of the specific energy in the fragmentation regime.
