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 ...

Biomimetic Intelligence and Robotics, 2022 The friction force is an important environmental factor that influences dynamic walking. While most of the related works simply assume static friction or Coulomb friction, we use the LuGre friction, which accounts for both static and dynamic effects, to ...

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.

Feel the Static and Kinetic Friction [PDF]
, 2012 Multimodal simulations augment the presentation of abstract concepts facilitating theoretical models understanding and learning. Most simulations only engage two of our five senses: sight and hearing. If we employ additional sensory communication channels in simulations, we may gain a deeper understanding of illustrated concepts by increasing the ...

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 ...

Heliyon, 2023 Shear thickening fluids (STFs) refer to non-Newtonian fluids of the dilatant variety, wherein their viscosity experiences a significant surge with an escalation in the shear rate. In this investigative work, the friction behavior between yarns (pull-out)

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.
