Shear Thickening of Dense Suspensions: The Role of Friction [PDF]
, 2019 Shear thickening of particle suspensions is characterized by a transition between lubricated and frictional contacts between the particles. Using 3D numerical simulations, we study how the inter-particle friction coefficient influences the effective ...

Shear friction capacity of self-consolidating concrete
Revista IBRACON de Estruturas e Materiais, 2020 An experimental research was developed to evaluate shear transfer in self-consolidating. Three concrete mixes were prepared, one conventional and two self-consolidating, differing on the proportion of the coarse and fine aggregate used.

Shearing the vacuum - quantum friction [PDF]
Journal of Physics: Condensed Matter, 1997 We consider two perfectly smooth featureless surfaces at T=0, defined only by their respective dielectric functions, separated by a finite distance, and ask the question whether they can experience any friction when sheared parallel to their interface. We find large frictional effects comparable to everyday frictional forces provided that the materials
