A Calibrated Comparison between P-α and Mesoscale Models for Shock Compaction of Granular Sugar

The supplementary material includes additional descriptions of (A) the experimental setup from Sheffield, Gustavsen, and Alcon. (1998), (B) the implementation of P − α modeling in continuum models, (C) mesoscale modeling in FLAG, and (D) cross-scale interpretation, which support the descriptions of the numerical methods and model parameters used in this study.
