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 ...

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) ...

Introduction Have you ever seen video footage of an avalanche or landslide rolling down a hill? Why is it that at one moment everything seems fine then suddenly the mountain begins to slump? This ...

The GranuDrum instrument is an automated powder flowability measurement technique predicated on the rotating drum principle. The drum is a horizontal cylindrical with transparent sidewalls and it is ...

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 ...

To measure the coefficient of static friction, change the angle on a ramp until a small wooden box slides downslope. One can change the contact surface to metal, add moisture, and change the weight of ...

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 ...
