Particle simulation of cohesive granular materials

We present two-dimensional molecular dynamics simulations of cohesive regul ar polygonal particles. The cohesive part of the force-law for the particle -particle interaction is validated by the agreement with existing experimen tal data. We investigate microscopic parameters, which axe not accessible t o experiments such as contact length, raggedness of the surface and correla tion time. With increasing cohesion, the particles move in clusters for lon g times.
