# On the genesis of directional friction through bristle-like mediating elements

@article{Gidoni2016OnTG, title={On the genesis of directional friction through bristle-like mediating elements}, author={Paolo Gidoni and Antonio DeSimone}, journal={arXiv: Mathematical Physics}, year={2016} }

We propose an explanation of the genesis of directional dry friction, as emergent property of the oscillations produced in a bristle-like mediating element by the interaction with microscale fluctuations on the surface. Mathematically, we extend a convergence result by Mielke, for Prandtl-Tomlinson-like systems, considering also non-homothetic scalings of a wiggly potential. This allows us to apply the result to some simple mechanical models, that exemplify the interaction of a bristle with a…

By focusing on the tensions in the elastic segments, this work shows that the evolution laws for the system are entirely analogous to the flow rules of elasto-plasticity, and shows that specific choices of the actuation strategy can lead to net displacements also in the direction of higher friction.

The shear failure and friction mechanisms of bioinspired adhesives consisting of elastomer arrays of microfibres terminated by mushroom-shaped tips are investigated in contact with a rigid lens and the extent of these mechanisms and their implications regarding static friction forces is found to depend on the crosstalk between the normal and lateral loading directions.
