On the friction dependency of the stress Lode angle
International Journal for Numerical and Analytical Methods in Geomechanics, 2023 AbstractThe shape of the failure locus of a material is significant for its strength predictions. Even when constitutive models include the same critical stress surface, different critical stress ratios can be predicted for an identical applied isochoric strain path.

The influence of particle size on the spread distance and angle of friction of granular materials [PDF]
E3S Web of Conferences, 2023 To produce a hazard map and thus provide mitigation measures against natural catastrophic events such as landslides, avalanches, and debris flows, it is necessary to determine the spread distance of such flows.

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 ...

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.
