• Force network ensemble for granular solids (DATA) 

  Tighe, B.P.; Eerd, A.R.T. van; Vlugt, T.J.H. (2009-03-31)

  Granular materials such as sand have both liquid-like and solid-like properties similar to both liquids and solids. Dry sand in an hour-glass can flow just like water, while sand in a sand castle closely resembles a solid. ...
