Abstract Scope |
The general goal of this work is to understand force distributions within three-dimensional (3D) disordered contact networks of frictional granular materials. The advancement of 3D in-situ experimental techniques has made it possible to characterize the packing configurations and forces in 3D frictional stiff granular media. This study leverages X-ray tomography and far-field high-energy diffraction microscopy (ff-HEDM) to investigate different granular material topics: (1) the effect of different confinement geometries on the force and contact networks of monocrystalline ruby spheres under uniaxial compression; (2) the validation of Janssen's law in a uniaxial compression test on monocrystalline ruby spheres; (3) the packing geometry of silicon cubes, rods, and plates under uniaxial compression. Discrete element method (DEM) simulations are conducted to supplement the experimental results. The findings from this work will enhance the understanding of force distribution and contact networks in 3D granular materials and help improve the modeling of 3D granular systems. |
