Anomalous density dependence of static friction in sand
Experimentally measured static friction force on the surface of a glass rod immersed in dry sand and the periodicity of the static friction force during gradual pulling out of the rod. Their observations demonstrate the central role of grain bridges and arches in the macroscopic properties of granular packings.
Force chain structure in a rod-withdrawn granular layer
The force-chain structure in a rod-withdrawn granular layer is experimentally investigated using a photoelastic technique. During the withdrawal, the development process of force chains is visualized by the photoelastic effect.
Packing-dependent granular friction exerted on a rod withdrawn from a granular layer: the role of shear jamming
Resistance force acting on a rod vertically withdrawn from a granular layer is studied by experiments and numerical simulations.
The pressure exerted by granular material: an application of the principles of dilatancy
