Fine powders and granular materials are extensively used in industrial applications. To manage and to enhance processing techniques, these materials have to be exactly characterized. The ...

Grain cargos like rice can shift suddenly at sea, altering a ship’s center of gravity and pushing it toward capsize. This breakdown explains angle of repose, reserve stability requirements, and the ...

The prediction of the angle of repose for raised mounds of dry cohesive granular material is a long-standing problem in the natural sciences and in industry. Using numerical (particle-based) ...

A heap is created when a powder is poured onto a surface. It is widely known that both the heap shape and the repose angle strongly rely on grain properties. Specifically, a non-cohesive powder forms ...

Growing up in a household where there was plenty of exposure to home construction cultivated a fascination with dirt and sand piles, necessary components of many varied projects in which a parent was ...

If slippery slopes are paved with good intentions, we now have the Transportation Department to thank for giving travel agents something new to slide around on. Let's say you're a travel agent and you ...
