Open AccessStability of rigid body motion through an extended intermediate axis theorem: application to rockfall simulation
The stability properties of a freely rotating rigid body are governed by the intermediate axis theorem, i.e., rotation around the major and minor principal axes is stable whereas rotation around the intermedia...

Reply to “Discussion of “The relation between dilatancy, effective stress and dispersive pressure in granular avalanches” by P. Bartelt and O. Buser (DOI: 10.1007/s11440-016-0463-7)” by Richard Iverson and David L. George (DOI: 10.1007/s11440-016-0502-4)
Iverson and George largely agree with our mathematical description of the dispersive pressure and dilatancy for a dry granular avalanche; however, they disagree with our views of effective stress and pore-flui...

The relation between dilatancy, effective stress and dispersive pressure in granular avalanches
Here we investigate three long-standing principles of granular mechanics and avalanche science: dilatancy, effective stress and dispersive pressure. We first show how the three principles are mechanically inte...
