摘要:Force networks may underlie the constitutive relations among granular solids and granular flows and inter-state transitions. However, it is difficult to effectively describe the anisotropy of force networks. We propose a new pair correlation function g(r, theta) to describe the characteristic lengths and orientations of force chains that are composed of particles with contact forces greater than the threshold values. A formulation g(r, theta) approximate to a(r)+b(r) cos2(theta-pi/2) is used to fit the g(r, theta) data. The characteristic lengths and orientations of force networks are then elucidated.
