Statistics regarding particle interactions in granular material of high density in
conditions of uniaxial compression

here is a close correlation between how stress evolves
in material characterised by high density and granularity
and contacting particle interactions. Statistics associated with
particle interactions and the relation of averaged local relative
motion with macroscopic motion are explored. This involves
assessment of howvalid the Voigt and Reuss assumptions are,
suggestion of how these assumptions can be extended, and
explorationof effects of history in the dense granularmaterial.
Three-dimensional quantitative simulations of dense granular
media subjected to uniaxial cyclical compression are used
to derive the necessary statistical samples. According to
outcomes, normal inter-particle forces are the main source
of stresses, while inter-particle frictional tangential forces do
not contribute directly to a significant extent. Nevertheless,
the particle contact time is markedly increased by tangential
friction, leading to a reduction in contact breakage rate. There
is evidence that the rate of contact breakage represents
a stress relaxation rate, and consequently, the extended
relaxation time causes a considerable increase in stress with
inter-particle friction.
