Abstract
This study introduces a novel micromechanical-based contact modeling approach to investigate granular material behavior and fabric formation. By deriving particle contact properties from micromechanical tests, the study aims to enhance the accuracy of discrete element method (DEM) simulations and gain insights into the multiscale behavior of granular materials. The evaluation of small-strain shear modulus (Gmax) behavior in quartz sand, along with the assessment of particle contact parameters, offers new perspectives on the roughness characteristics of granular materials. This innovative approach has the potential to advance our understanding of granular material behavior and inform the development of more accurate models with broad applications in science and engineering. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025
