Characteristics of Local Geomagnetic Field Variations and the Tectonic Stress Field Adjacent to the 21 May 2021, Ms 6.4 Yangbi Earthquake, Yunnan, China

open access: yesApplied Sciences, 2022
The tectonic processes leading up to an earthquake and the occurrence of the earthquake itself will cause local changes in the geophysical field (geomagnetic field, stress field, etc.).

Stress field characterisation in Nickel Rim South Mine using seismic stress inversion [PDF]

open access: yesProceedings of the International Conference on Deep and High Stress Mining, 2017
Knowledge of stresses is important for many aspects of mine design, but conventional methods of measuring stresses produce estimates at only a limited number of points in space and time. Furthermore, stresses are known to be affected by geological structures, particularly faults, but mapping of how the stress field is affected by such structures is not

Correlation between crustal anisotropy and seismogenic stress field beneath Shillong–Mikir Plateau and its vicinity in North East India

open access: yesGeomatics, Natural Hazards & Risk, 2021
A systematic study towards understanding the correlation between polarization direction of crustal anisotropy with seismogenic stress field at different locations of the Shillong-Mikir Plateau and its vicinity in North East India is attempted.

Regional stress field in Yunnan revealed by the focal mechanisms of moderate and small earthquakes

open access: yesEarth and Planetary Physics, 2019
We determined focal mechanism solutions of 627 earthquakes of magnitude M ≥ 3.0 in Yunnan from January 2008 to May 2018 by using broadband waveforms recorded by 287 permanent and temporary regional stations.

3D Residual Stress Field in Arteries: Novel Inverse Method Based on Optical Full‐field Measurements [PDF]

open access: yesStrain, 2012
Abstract:  Arterial tissue consists of multiple structurally important constituents that have individual material properties and associated stress‐free configurations that evolve over time. This gives rise to residual stresses contributing to the homoeostatic state of stress in vivo as well as adaptations to perturbed loads, disease or injury.

The Inversion Method Applied to the Stress Field around a Deeply Buried Tunnel Based on Surface Strain

open access: yesApplied Sciences, 2023
To identify the magnitude and direction of in situ stress in deeply buried tunnels, an inversion method for the stress field was proposed based on a finite number of measurement points of surface strain.

Determining the stress field in active volcanoes using focal mechanisms

open access: yesFrontiers in Earth Science, 2016
Stress inversion of seismological datasets became an essential tool to retrieve the stress field of active tectonics and volcanic areas. In particular, in volcanic areas, it is able to put constrains on volcano-tectonics and in general in a better ...

Strain-based forward modeling and inversion of seismic moment tensors using distributed acoustic sensing (DAS) observations

open access: yesFrontiers in Earth Science, 2023
This study used a waveform inversion of distributed acoustic sensing (DAS) data, acquired in two horizontal monitoring wells, to estimate the moment tensor (MT) of two induced microearthquakes.

Inversion of mining-induced stress field based on focal mechanism solutions: a case study of the 63upper06 working face in Dongtan Coal Mine

open access: yesFrontiers in Earth Science
Microseismic monitoring is pivotal for mine safety, offering early warnings for coal mining operations. By introducing the MTfit and MSATSI inversion methods to study the focal mechanisms of microseismic events and the stress field in coal mines, we ...

An inverse approach for constructing the residual stress field induced by welding

open access: yesThe Journal of Strain Analysis for Engineering Design, 2002
In this paper, an inverse approach based on the inherent strain method has been proposed for constructing the residual stress field induced by welding. Firstly, some smooth basis functions in the form of polynomials have been employed to approximate inherent strains.
