Molecular dynamics simulation of shear friction process in tectonically deformed coal
Frontiers in Earth Science, 2023 Shear friction is an important deformation process in tectonically deformed coals (TDCs) and is closely related to the dynamic metamorphism of coal. In the current study, we perform a molecular dynamics (MD) simulation of the shear friction process on ...

Journal of Experimental and Theoretical Physics Letters, 2002 We discuss crack propagation along the interface between two dissimilar materials. The crack edge separates two states of the interface, ``stick'' and ``slip''. In the slip region we assume that the shear stress is proportional to the sliding velocity, i.

Solids Under Extreme Shear: Friction‐Mediated Subsurface Structural Transformations [PDF]
Advanced Materials, 2019 AbstractTribological contacts consume a significant amount of the world's primary energy due to friction and wear in different products from nanoelectromechanical systems to bearings, gears, and engines. The energy is largely dissipated in the material underneath the two surfaces sliding against each other.

Experimental study on nonlinear friction behavior of granular flow lubrication
Results in Physics, 2022 Solid granules have good lubrication performance and load-bearing capacity, which has been concerned by researchers. However, the correlation mechanism between lubrication performance and granular medium dynamics is hardly focused on.

Friction of Shear-Fracture Zones [PDF]
Physical Review Letters, 2017 A shear fracture of brittle solids under compression undergoes a substantial evolution from the initial microcracking to a fully formed powder-filled shear zone. Experiments covering the entire process are relatively easy to conduct, but they are very difficult to investigate in detail. Numerically, the large strain limit has remained a challenge.
