Lawrence Livermore National Laboratory Granular Flow Project. Quarterly report, January-March 1986
- ed.
The objective of LLNL's Granular Flow Project is to develop an understanding for an ability to predict the flow behavior of granular solids. Our pursuit of this objective is primarily through the use of discrete particle computer models (i.e. molecular dynamics techniques) to simulate the flow of idealized granular materials. We initially modeled systems of smooth inelastic disks and, during the past year and a half, have increased the complexity of both the particles modeled and diagnostic algorithms monitoring the flow simulations so that, during the current reporting period, we conducted calculations with three-dimensional assemblies of equal-sized inelastic, frictional spheres undergoing steady rectilinear shearing flow. We examined the stress and velocity distribution in these systems and their sensitivity to various interparticulate interaction parameters. The results obtained in this initial generic study of shearing flow with frictional particles are still in the process of being evaluated. We report below highlights of results that have obtained to date. A more thorough evaluation of these calculations is underway and a more complete description of the study will be reported in the near future. 14 refs.
