The granular modeling is extended to describe visco-elastic response of dense particulate compound approaching to fine grained matrix with glassy phase with increase of the loading ratio. Of great importance in the present modeling is that the observed non-newtonian viscosity in these compounds should be caused by the particle-to-particle (or grain-to-grain) interaction and that rheological behavior of high dense compound must be governed by kinematical change of agglomerate or cluster of grains. Our developed mesoscopic modeling becomes an effective tool to describe the related rheology to superplastic deformation.
