Internal Friction of Angle Model of Particles [PDF]
, 2021 Abstract Currently, pressure from industry to streamline processes by creating their simulation models, and thus to gradual digitization is increasing. The essence of representative simulation models of bulk materials is to understand the principles and laws of the real behavior of particles.

Translational and rotational friction on a colloidal rod near a wall [PDF]
, 2010 We present particulate simulation results for translational and rotational friction components of a shish-kebab model of a colloidal rod with aspect ratio (length over diameter) $L/D = 10$ in the presence of a planar hard wall.

Frictional adhesion: a new angle on gecko attachment [PDF]
Journal of Experimental Biology, 2006 SUMMARYDirectional arrays of branched microscopic setae constitute a dry adhesive on the toes of pad-bearing geckos, nature's supreme climbers. Geckos are easily and rapidly able to detach their toes as they climb. There are two known mechanisms of detachment: (1) on the microscale, the seta detaches when the shaft reaches a critical angle with the ...

Particle friction angles in steep mountain channels [PDF]
Journal of Geophysical Research: Earth Surface, 2015 AbstractSediment transport rates in steep mountain channels are typically an order of magnitude lower than predicted by models developed for lowland rivers. One hypothesis for this observation is that particles are more stable in mountain channels due to particle‐particle interlocking or bridging across the channel width.
