WebJames D. Byerlee mostly deals with Geotechnical engineering, Pore water pressure, Mineralogy, Slip and Overburden pressure. His studies deal with areas such as Fault, Stiffness and Shear stress as well as Geotechnical engineering. His Shear stress study incorporates themes from Surface roughness, Fault mechanics, Fault friction and … WebMar 7, 2024 · The rate at which thermal pressurization proceeds depends primarily on the hydraulic characteristics of the surrounding porous medium, the coefficient of friction on the fault surface, and the slip velocity. If either the permeability exceeds 10 −15 m 2 or the porous medium compressibility exceeds 10 −8 Pa −1, then frictional melting may ...
Friction of rocks SpringerLink
WebThe rate and state dependent friction law based on laboratory experimental results has been widely accepted to describe the friction and sliding behavior of rock. In view of the fact that the traditional Coulomb friction law cannot be used to simulate the stick-slip of the fault, the rate and state dependent friction law is introduced into the developed continuum … In rheology, Byerlee's law, also known as Byerlee's friction law concerns the shear stress (τ) required to slide one rock over another. The rocks have macroscopically flat surfaces, but the surfaces have small asperities that make them "rough." For a given experiment and at normal stresses (σn) below about 2000 bars (200 MPa) the shear stress increases approximately linearly with the normal stress (τ = 0.85 σn, where σn is in units of MPa) and is highly dependent on roc… church of light cad model
Numerical simulation of the stick-slip of a straight strike-slip fault ...
WebThis is because at low stress rock friction is strongly dependent on surface roughness. At high normal stress that effect is diminished and the friction is nearly independent of rock … WebByerlee friction: best-fit relationships between shear stress at maximum friction versus normal stress for er~, < 200 MPa and a~, > 200 MPa for a broad range of rock types (after BYERLEE, 1978), plus church of living dangerously
