When grains are added to a cylinder, the weight at the bottom is smaller than the total weight
of the column, which is partially supported by the lateral walls through frictional interactions …

The angle of repose and characteristics of the base stress distribution underneath granular
piles serve as essential indicators in understanding the mechanical and packing properties …

Biomass-coal co-gasification technology is a new approach that considers both energy
demand and carbon emission reduction policies. A comprehensive understanding of flow …

Although the pressure dip in conical sandpiles has been studied for several decades, this
counterintuitive phenomenon is still not fully understood due to the intrinsic complexity of …

Sandpiles are ubiquitous in nature and engineering applications but still not fully understood
due to the complexity of structures and materials properties. This work presents a systematic …

The repose angle and characteristics of the vertical stress distribution beneath the sandpile
can help to understand the physical and mechanical properties of the granular matter and …

We studied an interesting experiment that showed a half-buried chopstick lifting a full bottle
of granules off the table. In Janssen theory, the friction force provided by the container wall …
