Sensitivity of Coulomb stress change to the parameters of the Coulomb failure model: A case study using the 2008 Mw 7.9 Wenchuan earthquake

Journal of Geophysical Research: Solid Earth, 2014
The Coulomb stress change has been widely employed to interpret mainshock-mainshock and mainshock-aftershock triggering as well as interactions amongst earthquake faults and volcanoes.

Earthquakes and Coulomb stress evolution in a diffuse plate boundary

, 2016
Diffuse plate boundaries are characterized by deformation distributed over a wide area in a complex network of active faults, and by low strain rates. These characteristics make it difficult to understand the spatial and temporal distribution of seismicity. The northern Basin and Range Province (BRP) in the western United States is an excellent example

Changes of Coulomb Failure Stress during Stimulation

Proceedings, 2011
For the prediction of future reservoir performance, knowledge of the spatio-temporal evolution of the geothermal reservoir in response to stimulation and production is a key issue. During the project for developing an Enhanced Geothermal System at Soultz-

Melting Dynamics in Thermal and Stress Driven Coulomb Clusters

Physica Scripta, 2001
The microscopic dynamical responses of a two dimensional circular Coulomb cluster to thermal excitations and to the external force along a narrow band through its center are studied. The strong competition between the cirular boundary and the inner domain with triagular lattice leads to the nonuniform melting of the cluster.

Modified Mohr-Coulomb Theory for Triaxial State of Stress

Applied Mechanics and Materials, 2015
The Mohr-Coulomb failure theory presents the major drawback that can be applied only for plane state of stress. In this paper, we propose a modification of the Mohr-Coulomb theory that might eliminate this disadvantage. It is proposed to replace the three Mohr's circles for spatial state of stress with one “virtual circle” with diameter σ1-σ3±2ρ ...

Dynamic Stresses, Coulomb Failure, and Remote Triggering

Bulletin of the Seismological Society of America, 2008
Dynamic stresses associated with crustal surface waves with 15–30-sec periods and peak amplitudes 5 km). The latter is consistent with the observation that extensional or transtensional tectonic regimes are more susceptible to remote triggering by Rayleigh-wave dynamic stresses than compressional or transpressional regimes.

Consistent Regularization of Induced Coulomb Stresses in Displaced Faults

2023
This note provides unregularized and regularized closed-form analytical expressions for the depletion-induced or injection-induced pre-slip Coulomb stresses in two-dimensional displaced dip-slip faults. The regularization serves to remove logarithmic singularities and jump-discontinuities in the unregularized formulation.

Predicting ductile fracture of low carbon steel sheets: Stress-based versus mixed stress/strain-based Mohr–Coulomb model

International Journal of Solids and Structures, 2013
International audienceTwo distinct implementations of the Mohr-Coulomb failure model are used in conjunction with a non-associated quadratic plasticity model to describe the onset of fracture in low carbon steel sheets.

The Stress Triggering of Aftershocks by Badong M5.1 Mainshock from Coulomb Stress Changes

Advanced Materials Research, 2014
TheCoulomb stress changes are usually adopted to make analysis on faultinteractions and stress triggering. This paper mainly deals with Coulomb stresschange of mainshock and affect on aftershocks. We preliminarily conclude thatthe mainshock produce Coulomb stress change on aftershocks most behavingpositive and triggered them.

Erratum to Dynamic Stresses, Coulomb Failure, and Remote Triggering

Bulletin of the Seismological Society of America, 2009
Figure 13h on page 84 in Hill (2008) illustrating the triggering potential of Rayleigh waves with strike-normal incidence on reverse faults at a depth of 10 km is incorrect. The corrected version of Figure 13 is reproduced here. The correction involves exchanging the stress orbits on the left-hand side of the Mohr’s circle in Figure 13h with those on ...
