Fracture energy and breakdown work during earthquakes

M Cocco, S Aretusini, C Cornelio… - Annual Review of …, 2023 - annualreviews.org
Large seismogenic faults consist of approximately meter-thick fault cores surrounded by

How frictional slip evolves

S Shi, M Wang, Y Poles, J Fineberg - Nature Communications, 2023 - nature.com
Earthquake-like ruptures break the contacts that form the frictional interface separating
contacting bodies and mediate the onset of frictional motion (stick-slip). The slip (motion) of …

A synthesis of fracture, friction and damage processes in earthquake rupture zones

Y Ben-Zion, G Dresen - Pure and Applied Geophysics, 2022 - Springer
We review properties and processes of earthquake rupture zones based on field studies,
laboratory observations, theoretical models and simulations, with the goal of assessing the …

Analysis of stress drop behavior for stick-slip friction based on total reflection observation experiment

J Ding, H Wu, J Han, S Yan - Tribology International, 2024 - Elsevier
This paper employed an experimental system based on the total reflection method to study
the contact interface behavior during the stress drop process of stick-slip friction. The two …

Mechanical energy dissipation during seismic dynamic weakening in calcite‐bearing faults

S Aretusini, A Nuñez Cascajero… - Journal of …, 2024 - Wiley Online Library
Earthquakes are frictional instabilities caused by the shear stress decrease, that is, dynamic
weakening, of faults with slip and slip rate. During dynamic weakening, shear stress …

Earthquakes as dynamic fracture phenomena

Z Reches, J Fineberg - Journal of Geophysical Research: Solid …, 2023 - Wiley Online Library
A large earthquake unlocks a fault‐zone via dynamic rupture while releasing part of the
elastic energy stored during the interseismic stage. As earthquakes occur at depth, the …

The initiation of frictional motion—The nucleation dynamics of frictional ruptures

S Gvirtzman, J Fineberg - Journal of Geophysical Research …, 2023 - Wiley Online Library
Frictional interfaces lose stability via earthquake‐like ruptures, which are close analogues of
shear cracks that are well‐described by fracture mechanics. Interface ruptures, however …

Experimental and analytical studies on the influence of weathering degree and ground-environment analog conditions on the tribological behavior of granite

CS Sandeep, H He, K Senetakis - Engineering Geology, 2022 - Elsevier
Weathering is a geological/geo-environmental process that degrades and transforms rocks,
contributing to landslides and instability of geo-systems and infrastructures. The effects of …
