摘要: We consider the problem of hard spheres shearing from rest with hydrodynamic lubrication, but no Brownian forces. A theoretical model is presented, in terms aggregation elongated clusters particles, and predicts a jamming transition, where stress average cluster size tend to infinity after finite amount strain. The compared simulation data [Europhys. Lett. 32, 535 (1995)], critical volume fraction above which will occur macroscopic systems.
