Application of the Modified Mohr–Coulomb Yield Criterion in Seismic Numerical Simulation of Tunnels

Shock and Vibration, 2021
To solve the classical problem that the Mohr–Coulomb yield criterion overestimates the tensile properties of geotechnical materials, a modified Mohr–Coulomb yield criterion that includes both maximum tensile stress theory and smooth processing was ...

Nanoscale Mapping of Plasmonic Charge Transport in Nano‐Resonators Based on Resistive Switching Materials

Advanced Functional Materials, EarlyView.
In this strategy, a conductive nano‐probe is employed to induce nanoscale phase transitions and map the nanoscale conductivity and trap density of GST films. By utilizing the contrasting properties of phase‐change states, nano‐resonators are fabricated that exhibit plasmonic conduction and dramatically different transport characteristics.

Importance of forearc topography for the triggering of aftershocks of megathrust earthquakes: insights from mechanical models and the Tohoku-Oki and Maule earthquakes [PDF]

Solid Earth
Aftershocks of megathrust earthquakes at subduction zones may be driven by stresses arising from the topography of the forearc. However, the effect of topographic stresses on aftershock triggering is quantitatively not well understood and has been ...

祁连—海原断裂带库仑应力演化及地震危险性

Dizhen xuebao, 2022
祁连—海原断裂带是青藏高原东北缘重要的活动断裂带，调节着青藏高原北东向推挤作用和阿拉善地块的东西向运动。已有地震地质和数值模型结果显示，祁连—海原断裂带目前存在几个强震破裂空段且其上应力积累显著、断层闭锁程度高，2022年1月8日门源MS6.9地震即发生在祁连—海原断裂带西段的断层高闭锁、应力积累显著的破裂空段。为进一步认识祁连—海原断裂带未来的强震危险性，本文收集整理了青藏高原北部的强震破裂模型，并基于分层黏弹性流变模型计算了青藏高原北部1900年以来的强震对祁连—海原断裂带的库仑应力加载。结果显示 ...

The 2007 Azores earthquakes: A case of triggering? [PDF]

, 2009
On 5 April (Mw=6.3) and 7 April 2007 (Mw=6.1 ) two earthquakes occur at the Formigas Islets (Azores Islands), both with same epicenter and felt (I=V/VI MSK) in S. Miguel Island.

Evidence for Anthropogenic Surface Loading as Trigger Mechanism of the 2008 Wenchuan Earthquake

, 2011
Two and a half years prior to China's M7.9 Wenchuan earthquake of May 2008, at least 300 million metric tons of water accumulated with additional seasonal water level changes in the Minjiang River Valley at the eastern margin of the Longmen Shan.

Stress loading history of earthquake faults influenced by fault/shear zone geometry and Coulomb pre-stress [PDF]

Scientific Reports, 2020
AbstractWhether the stress-loading of faults to failure in earthquakes appears to be random or to an extent explainable, given constraints on fault/shear-zone interaction and the build-up and release of stress over many earthquake cycles, is a key question for seismic hazard assessment.

Beyond the Edge: Charge‐Transfer Excitons in Organic Donor‐Acceptor Cocrystals

Advanced Functional Materials, EarlyView.
Complex excitonic landscapes in acene–perfluoroacene cocrystals are unveiled by polarization‐resolved optical spectroscopy and many‐body theory. This systematic study of a prototypical model system for weakly interacting donor–acceptor compounds challenges common views of charge‐transfer excitons, providing a refined conceptual framework for ...

Sensitivity of the Static Earthquake Triggering Mechanism to Elastic Heterogeneity and Main Event Slip [PDF]

, 2013
This paper has evolved out of our previous work on static stress transfer, where we used the full-space elastostatic Green's tensor to compute the Coulomb stress transfer impact of the Landers earthquake on the Hector Mine event. In this work, we use the
