Force transmission in highly polydisperse granular media

摘要: This work is devoted to the numerical modeling of highly polydisperse granular materials in view investigating texture and mechanical behavior quasi‐static shearing. The polydispersity modeled terms size span curvature particle distributions. A method proposed generate representative distributions both number volume classes, accessible parameters are determined for tractable particles. geometrical used construct large samples study resulting a systematic manner as function distribution. These then subjected simple shear with periodic boundary conditions by means contact dynamics method. We show that: 1) highest level solid fraction corresponds uniform distribution fractions; 2) strength steady state independent polydispersity; 3) detailed analysis force transmission indicat...
