CHARACTERIZATION OF MICRO-MECHANICAL PROPERTIES OF GRANULAR MATERIALS BASED ON THE USE OF 3D-T IMAGERY AND DISCRETE ELEMENT MODELING
MetadataShow full item record
This study analyzes the effects of varying conditions for the assessment of micro-parameters of granular materials based on both laboratory and numerical experiments. The aim is to investigate the effects of varying micro-parameters of particle elements and the interactions between them under controlled conditions. For this purpose, a homogenous specimen is built using particles made out of steel spheres with constant diameter. The experiment where the micro-parameters are analyzed consists on assessing a simple kinematic exercise defined by the sample preparation, by the use of the dry pluviation technique, where spheres are dropped at varying heights to achieve different densities. A numerical model is built to reproduce the same experimental conditions by the use of distinct elements using PFC-3D. This allows for a direct comparison to achieving a better understanding on the assessment of micro properties of granular materials. The outcomes of this study also permit to conduct uncertainty quantification on the assessment of the micro-parameters.
