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) ...

Angle of Repose(θ R): The angle between the surface of the powder pile and the horizontal plane to which a material can be piled without slumping is called the angle of repose. θ R = tan-1 (h/r) Angle ...

IT is well known that the friction of solids on snow surfaces is larger than on ice surfaces. The higher kinetic friction obtained on snow is attributed to the extra work done in displacing and ...

Geophysicists solve a key problem in physics and provide results that can be applied in such diverse areas as planetary research and 3-D printing / publication in ‘PNAS’ The prediction of the angle of ...

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 ...

It was a beautiful bluebird powder day off the backside of Snowbowl, Montana. A storm had deposited 10 inches of low-density snow and I was excited to drop into the run. As I approached the ridge, I ...
