The slope of the friction law of hertzian-asperity--based metainterfaces has a finite positive lower bound
Julien Scheibert
Metainterfaces can realize specified evolutions of their friction force as a function of the confining normal force (friction law), thanks to the design of the individual radii and…
Automated Discovery of Metainterfaces with Tailored Friction Laws
Li Fu, Djibril Gabriel Kashala, D. Dalmas +1
Providing dry solid contacts with on-demand macroscale frictional behaviour remains a formidable challenge in tribology, haptics or robotics. Metainterfaces created from surfaces w…
Normal contact of metainterfaces: the roles of finite size and microcontact interactions
Donald Zeka, Nawfal Blal, Fatima-Ezzahra Fekak +3
The design of contact interfaces that meet quantitatively a specified friction law (friction force vs normal force) is challenging due to the multi-scale and multi-physics nature o…
Non-monotonic evolution of contact area in soft contacts during incipient torsional loading
Bo Zhang, Mariana de Souza, Daniel M. Mulvihill +3
Many properties of soft contact interfaces are controlled by the contact area (e.g. friction, contact stiffness and surface charge generation). The contact area increases with the…
