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
