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 ...

The underlying mechanism is investigated using discrete element methods simulations.

Granular flow dynamics and collapse mechanisms represent a rapidly evolving area of research that spans fundamental physics, geotechnical engineering and natural hazard assessment. At its core, the ...

If static, this problem is straightforward to solve using FE software because the nonmoving material can be treated as a solid. But attempting to simulate the unloading of the hopper would complicate ...

Granular flow, typified by debris and rock avalanches, poses significant challenges for the structural integrity of rigid barriers. These high-energy flows exhibit complex behaviours influenced by ...

New findings describe the dynamics of the clog of icebergs -- known as an ice mélange -- in front of Greenland's Jakobshavn Glacier. The fast-moving glacier is considered a bellwether for the effects ...

There's rarely time to write about every cool science-y story that comes our way. So this year, we're once again running a special Twelve Days of Christmas series of posts, highlighting one science ...

MADISON - A handful of sand contains countless grains, which interact with each other via friction and impact forces as they slip through your fingers. When a handful becomes a load in an excavator ...

As Earth’s climate systems change, polar sea ice is becoming more granular in structure. University of Utah-led research ...

Almost every manufacturing industry has to deal with powders and granules at some stage during production. Depending on the nature of your powders, you will have different testing priorities. For ...

Suppose a hopper is filled with a granular material such as sand, and you need to compute the force or stress on the hopper walls. If static, this problem is straightforward to solve using FE software ...
