Ray-like force propagation and isotropic packs
We showed that sequential
packs show ray-like force propagation
They are built anisotropically, so the direction of propagation is unambiguous
However, the ray-like propagation equation doesnÕt require anisotropy; only isostaticity
What defines the ray direction
in an isotropic pack?
Construction of the pack cannot
matter
Only source of anisotropy is the
boundary.
(Isotropic) distorted square lattice can test this notion:
floor supports bottom row of
particles
