Unjamming in a 3D Granular System: The Micromechanical Role of Friction in Force Distributions and Rheological Properties
Vicente Salinas, Héctor Alarcón, Eduardo Rojas +2
In this work, we investigate the unjamming transition in a three-dimensional granular system composed of frictional spheres, in which the packing fraction is systematically reduced…

Fluid Motion Makes the Bottle-Flip Challenge Mechanically Unintuitive But Viable
Patricio Morales, Victor Ahumada, Leonardo Gordillo +1
The bottle-flip challenge -- the upright landing of a partially filled bottle after tossing and flipping it in the air -- unexpectedly became a viral mechanics exercise. Through hi…
