Viscoelasticity of granular materials
Mechanics of Materials, 1995 Abstract In a former work (V.T. Granik and M. Ferrari (1993), Microstructural mechanics of granular media, Mech. Mater. 15, 301–322) a micromechanical theory for elastic granular media was deduced on the basis of the identification of the constituent grains with the nodes of a Bravais lattice.
