Analysis of the Variation of Friction Coefficient of Sandstone Joint in Sliding

Advances in Civil Engineering, 2020
The friction coefficient of rock joints is closely related to the stability of the slope. However, it is difficult to predict the friction coefficient due to the influence of surface roughness and mechanical properties of rocks.

Attractiveness of periodic orbits in parametrically forced systemswith time-increasing friction [PDF]

, 2012
We consider dissipative one-dimensional systems subject to a periodic force and study numerically how a time-varying friction affects the dynamics. As a model system, particularly suited for numerical analysis, we investigate the driven cubic oscillator ...

Wall slip of complex fluids: interfacial friction or slip length? [PDF]

, 2018
Using a dynamic Surface Force Apparatus, we demonstrate that the notion of slip length used to describe the boundary flow of simple liquids, is not appropriate for viscoelastic liquids.
