PARTICLE SIMULATION OF COHESIVE GRANULAR MATERIALS

We present two-dimensional molecular dynamics simulations of cohesive regular polygonal particles. The cohesive part of the force-law for the particle–particle interaction is validated by the agreement with existing experimental data. We investigate microscopic parameters, which are not accessible to experiments such as contact length, raggedness of the surface and correlation time. With increasing cohesion, the particles move in clusters for long times.
