Abstract
A vector lattice model for stresses in granular materials is proposed. A tw o-dimensional pile built by pouring from a point is constructed numerically according to this model. Remarkably, the pile violates the Mohr Coulomb st ability criterion for granular matter, probably because of the inherent ani sotropy of such poured piles. The numerical results are also compared to th e earlier continuum fixed principal axes model and the (scalar) lattice q-m odel.
