## Description

- description: 'This study develops a Bayesian optimization framework to calibrate
    two discrete element method (DEM) parameters—the cohesion-related surface energy
    coefficient (k) and the rolling resistance coefficient (µr)—based on experimental
    void ratio data obtained from powder consolidation tests. '
