Analysis of friction among grain particles in warehousebased on finite element method
Liang you shipin ke-ji, 2019 In order to investigate the stress distribution between grain particles and the distribution of relative static friction between grain particles and silo walls, the ideal elastic-plastic constitutive relationship and Drucker-prager yield criterion were ...

Emergent friction in two-dimensional Frenkel-Kontorova models [PDF]
, 2016 Simple models for friction are typically one-dimensional, but real interfaces are two-dimensional. We investigate the effects of the second dimension on static and dynamic friction by using the Frenkel-Kontorova (FK) model.

How static is static friction? [PDF]
Proceedings of the National Academy of Sciences, 2008 Physics 101 wisdom suggests that we need to overcome the static friction force, Fs, to initiate the lateral motion of one solid body over another one and that a force greater than the kinetic friction, Fk, is required to maintain the gliding nature of the contact. To drag a solid through a fluid, no such threshold forces exist.

Friction anisotropy at Ni(100)/(100) interfaces: Molecular dynamics studies [PDF]
, 2002 The friction of surfaces moving relative to each other must derive from the atomic interaction at interfaces. However, recent experiments bring into question the fundamental understanding of this phenomenon.

Static friction between rigid fractal surfaces [PDF]
Physical Review E, 2015 Using spheropolygon-based simulations and contact slope analysis, we investigate the effects of surface topography and atomic scale friction on the macroscopically observed friction between rigid blocks with fractal surface structures. From our mathematical derivation, the angle of macroscopic friction is the result of the sum of the angle of atomic ...

The Statistical Characteristics of Static Friction [PDF]
International Journal of Applied Mechanics, 2018 Friction is one of the fundamental issues in physics, mechanics and material science with many practical applications. However, the understanding of macroscopic friction phenomena from microscopic aspect is still on the way. In this paper, molecular dynamics simulations are performed to investigate the static friction between two planar crystal ...

The Stress Transmission Universality Classes of Periodic Granular Arrays [PDF]
, 2000 The transmission of stress is analysed for static periodic arrays of rigid grains, with perfect and zero friction. For minimal coordination number (which is sensitive to friction, sphericity and dimensionality), the stress distribution is soluble without
