Bimodal self-assembly of granular spheres under vertical vibration

R Amirifar, K Dong, Q Zeng, X An - Soft Matter, 2019‏ - pubs.rsc.org
As granular particles in a packing are athermal, their self-assembly has to be realized with
the input of energy via walls. But different manners of energy input, eg, through tap** or …

Study of the transition from amorphous to crystalline phase in a granular system under shearing and vibration
