Sensing and Quantifying a New Mechanism for Vehicle Brake Creep Groan
Shock and Vibration, 2019 This paper investigates the creep groan of a vehicle’s brake experimentally, analytically, and numerically. Experimentally, the effects of acceleration on caliper and strut, noise, brake pressure, and tension are measured.

Stick‐Slip Tremor Beneath an Alpine Glacier
Geophysical Research Letters, 2021 Sliding of glacial ice over its base is typically described by a frictionless or slowly deforming bed. This view is challenged by recent seismic observations of stick‐slip motion at the ice‐bed interface.

Distinct stick-slip modes in adhesive polymer interfaces
, 2017 Stick-slip, manifest as intermittent tangential motion between two solids, is a well-known friction instability that occurs in a number of natural and engineering systems.

Correlation between stick-slip frictional sliding and charge transfer
, 2010 A decade ago, Budakian and Putterman (Phys. Rev. Lett., {\bf 85}, 1000 (2000)) ascribed friction to the formation of bonds arising from contact charging when a gold tip of a surface force apparatus was dragged on polymethylmethacrylate surface.

The effect of laser surface texturing to inhibit stick-slip phenomenon in sliding contact
Advances in Mechanical Engineering, 2019 Stick-slip phenomenon in some mechanical structures, especially in machine tools, should be eliminated or inhibited, otherwise the vibration will occur and the position error will inevitably be obtained. In this study, different kinds of surface textures

Stick-slip friction and nucleation dynamics of ultra-thin liquid films
, 2001 We develop the theory for stick-slip motion in ultra-thin liquid films confined between two moving atomically-flat surfaces. Our model is based on hydrodynamic equation for the flow coupled to the dynamic order parameter field describing the ``shear ...

Tremor during ice stream stick-slip [PDF]
The Cryosphere, 2015 Abstract. During the 200 km-scale stick slip of the Whillans Ice Plain (WIP), West Antarctica, seismic tremor episodes occur at the ice–bed interface. We interpret these tremor episodes as swarms of small repeating earthquakes. The earthquakes are evenly spaced in time and this even spacing gives rise to spectral peaks at integer multiples of the ...

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Numerical Study on Characteristics of Stick-Slip Instability of Coal-Rock Parting-Coal Structure under Lateral Unloading [PDF]
LithosphereUnloading excavation can increase the possibility of rock burst, especially for coal seam with rock parting. In order to explore the evolution process of rock burst under lateral unloading, the combination of in situ measures and numerical experiments is
