During FY85 LLNL's Granular Flow Project has been primarily concerned with developing new discrete particle computer models for simulating the flow behavior of granular solids and determining their rheological characteristics. Calculations of effective viscosity, granular-temperature and stresses performed with our new two-dimensional steady-state shearing model for inelastic, frictional disks have been reported previously (1,2). During the current reporting period most of our efforts have been directed toward completing an initial version of a three-dimensional model capable of doing similar calculations for assemblies of inelastic spheres. Some aspects of this model development effort were very straight forward extensions of our two-dimensional model, while others required significant new development effort.
