The role of asperity indentation and ploughing in rock friction — I: Asperity creep and stick-slip
TLDR
In this article, the authors identified two processes which produce stick-slip instability in the frictional slliding of rock and identified the Bowden and Tabor adhesion theory to predict frictional behavior of rock when brittle fracture of asperities is inhibited.About:

The Mechanics of Earthquakes and Faulting
TL;DR: The connection between faults and the seismicity generated is governed by the rate and state dependent friction laws -producing distinctive seismic styles of faulting and a gamut of earthquake phenomena including aftershocks, afterslip, earthquake triggering, and slow slip events.
Journal ArticleDOI
Friction of Rocks
TL;DR: This paper showed that at low normal stress the shear stress required to slide one rock over another varies widely between experiments and at high normal stress that effect is diminished and the friction is nearly independent of rock type.
Journal ArticleDOI
Modeling of rock friction: 1. Experimental results and constitutive equations
TL;DR: In this paper, it is shown that the strength of the population of points of contacts between sliding surfaces determines frictional strength and that the number of contacts changes continuously with displacements.
Journal ArticleDOI
Earthquakes and friction laws
TL;DR: The traditional view of tectonics is that the lithosphere comprises a strong brittle layer overlying a weak ductile layer, which gives rise to two forms of deformation: brittle fracture, accompanied by earth-quakes, in the upper layer, and aseismic ductile flow in the layer beneath as mentioned in this paper.
Journal ArticleDOI
Laboratory-derived friction laws and their application to seismic faulting
TL;DR: In this article, a review of the relationship between friction and the properties of earthquake faults is presented, as well as an interpretation of the friction state variable, including its interpretation as a measure of average asperity contact time and porosity within granular fault gouge.

The friction and lubrication of solids
Frank Philip Bowden,David Tabor +1 more
TL;DR: Tabor and Bowden as mentioned in this paper reviewed the many advances made in this field during the past 36 years and outlined the achievements of Frank Philip Bowden, and reviewed the behavior of non-metals, especially elastomers; elastohydrodynamic lubrication; and the wear of sliding surfaces.

Stick-slip as a mechanism for earthquakes.
W. F. Brace,James D. Byerlee +1 more
TL;DR: Stick-slip often accompanies frictional sliding in laboratory experi ments with geologic materials and may represent stick slip during sliding along old or newly formed faults in the earth.

Direct Measurements of the Surface Energies of Crystals
TL;DR: In this paper, the surface energies of several simple crystals have been measured at −196°C by means of quantitative cleavage experiments and the measured values of their respective surface energies (ergs/cm2) are: 340, 1200, 450, 280, 230, 1240, and 105.

Time‐dependent friction in rocks
TL;DR: Friction experiments have been conducted on porous sandstone, quartzite, graywacke, and granite in the 20-to 850-bar normal stress range as mentioned in this paper, and the coefficient of static friction of surfaces with gouge exhibits a highly time-dependent behavior.
