3D analog and numerical experiments on grain comminution

This dataset contains data from analog and numerical experiments, both subsets investigate the comminution of grains under simple shear conditions. The analog subset contains photographs (.jpg) of 6 analog experiments performed in the ring shear apparatus designed at the Structure Lab of Iowa State University—taken before, halfway, and after the experiments. In addition, “CF_LG” contains a video (.mov) in real time (30 minute 30 seconds); “CF_D” contains a 52-second video (.mp4) that corresponds to 30 minute 30 seconds in real time. The numerical subset contains input files (.csv), scripts (.py, .prm), and videos (.avi) from 8 numerical experiments performed using the open-source Discrete Element code ESyS-Particle version 2.3.5. The numerical experiments are benchmarked by the analogy experiments, and each 25-second video corresponds to 15 minute 50 seconds in real time.
