Directional commensurability stabilizes structural superlubricity in patterned mesoscale interfaces
Viet Hung Ho, Ge Li, Melisa M. Gianetti +3
Structural superlubricity, arising from lattice incommensurability, offers a promising route to eliminate friction and associated energy losses in mechanical systems. In real-world…
Nonuniform pressure helps structural superlubricity
Melisa M. Gianetti, Viet Hung Ho, Bjørn Haugen +2
Structural superlubricity, nearly vanishing friction between two structurally incommensurate crystalline surfaces, is a promising avenue for reducing friction in applications, but…
Single-Contact Problem in Atomically Flat Interfaces: a Simulation Approach
Rui Dong, Ahmed Uluca, Graham Cross +1
Understanding friction at single-asperity contacts is essential for bridging the gap between nanoscale structural superlubricity and realistic tribological systems dominated by Her…
Kinetic theory applied to pressure-controlled shear flows of frictionless spheres between rigid, bumpy planes
Dalila Vescovi, Astrid S. de Wijn, Graham L. W. Cross +1
We numerically investigate, through discrete element simulations, the steady flow of identical, frictionless spheres sheared between two parallel, bumpy planes in the absence of gr…
