Titel:
From discrete element simulations to a continuum model 
Abstract:
One of the essential questions in material sciences and especially in the area of granular matter is, how to obtain macroscopic quantities like velocity-field, stress or strain from "microscopic" quantities like contact-forces and -deformations as well as particle-displacements and rotations in a granular assembly. We examine a two-dimensional shear-cell by means of discrete element simulations and compute kinematic quantities like the velocity field, the elastic deformation gradient and the def...    »
