We present two-dimensional molecular dynamics simulations of cohesive regular polygons. We investigate the dependence of the angle of respose from the cohesion, which is in good agreement with experiments. Using this as validation, we investigate microscopic parameters which are not accessible to the experiment. This includes contact length, raggedness of the surface and correlation time.
