LIMITATIONS ON THE APPLICABILITY BYERLEE

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… WebByerlee's law is an experimentally derived law in physics that gives the stress circumstances in the Earth's crust at which fracturing along a geological fault takes place. … WebShear stress/depth plots for modelling material and for the upper crust (Byerlee law, 1978).
