Summary

Many of the observed but yet unexplained phenomena associated with granular flow have been attributed to the development of a layered microstructure within the material. In particular the microstructure development has been called on to explain many of the experimental observations that cannot be accounted for in the presently available theoretical studies. While the attributions are based on sound physical arguments, the complexity of the processes involved has prohibited the inclusion of microstructure development in theoretical models. As a result no one has yet demonstrated how and to what extent the microstructure can account for the phenomena to which it has been ascribed. This paper addresses the effect of microstructure development for two dimensional flows by incorporating a heuristic model of the microstructure into a simple theoretical analysis.
