Visualization of force networks in 2D dense granular materials

Jianguo LIU, Qicheng SUN, Feng JIN,

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 1,   Pages 109-115 doi: 10.1007/s11709-010-0003-8

Abstract: To understand the structure and evolution of force chains, a photoelastic technique was improved forThe interparticle contact force distribution was found a peak around the mean value, a roughly exponentialtail for greater force and a dip toward zero for smaller force.The force chain network around the probe tip was depicted, and the contact angle distribution of particlesin force chains was found to be well aligned in the directions of major principal stress.
