Angular grain fragmentation with DEM modeling: application to fault gouge shearing

This dataset regroups DEM-based data with grain fragmentation of angular particles. All simulations were performed with the open-source software MELODY version 3.95 and 4.00dev (DOI: 10.5281/zenodo.4305614) developed and described in Mollon (2018). The code is available for downloading at https://github.com/GMollon/MELODY2D. We gathered here data from: a Brazilian test to simulate single-grain fragmentation, an oedometric model to assess multi-grain breakage under compression, and a shearing fault gouge model to capture progressive particle breakage, grain rearrangement, and potential strain localization.
