Abstract

Granular material packing is of considerable importance when considering the stability and shear strength of granular media. In this study, granular material packing at the grain scale is studied to see how packing is influenced by inherent particle characteristics such as shape, angularity and surface texture. Studies will show clear evidence of the influence of these factors on the granular packing obtained. Materials tested include glass beads, natural sands and a manufactured sand of varying shape, angularity and surface texture. X-ray CT is employed for imaging and 3-D volumetric reconstruction of sample assemblages. Image and volumetric processing routines are then performed on these reconstructions to measure local variations in packing density and generate density maps. In this paper, we demonstrate the success of our technique by exercising the method on several sets of granular particles.
