The underlying mechanism is investigated using discrete element methods simulations.

When we take a stroll on the beach, we walk on the sand without any trouble. The sand appears solid and is difficult to compress. When we put the same sand grains in an hourglass, they behave very ...

Granular flow dynamics encompasses the study of particulate matter in motion which, unlike conventional fluids, display both solid-like and fluid-like characteristics. The field investigates the ...

University of Chicago physicists have made careful measurements of flowing sand that can help resolve longstanding questions regarding how glasses differ from liquids at the atomic level, the ...

CAMBRIDGE, Mass. -- Sand in an hourglass might seem simple and straightforward, but such granular materials are actually tricky to model. From far away, flowing sand resembles a liquid, streaming down ...
