Correlation of microseismic and chemical properties of brittle deformation in Locharbriggs sandstone [PDF]

, 2003
The time-dependent properties of ceramic materials such as rocks depend both on preexisting cracks and chemical properties acting at their tips. We have examined the direct effect of chemical processes on the growth of a crack population by carrying out ...

Integrating the Finite Element Method with Python Scripting to Assess Mining Impacts on Surface Deformations

Applied Sciences
Mining operations disrupt the structure of rock layers, leading to surface deformations and potential mining damage. This issue has been extensively studied since the 19th century using various analytical, geometric-integral, and stochastic methods ...

Surface Deformation Associated with the 22 August 1902 Mw 7.7 Atushi Earthquake in the Southwestern Tian Shan, Revealed from Multiple Remote Sensing Data

Remote Sensing, 2022
The 22 August 1902 Mw 7.7 Atushi earthquake is the most disastrous seismic event in the southwestern Tian Shan. However, the spatial distribution of surface rupture zones as well as the geometric feature of surface deformation remain unclear, and the ...

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Study on deformation characteristics of room-and-pillar mined-out area based on physical simulation test

Meitan kexue jishu
The room-and-pillar mined-out area has the characteristics of small recovery rate and large coal pillar, and its overburden movement law and surface deformation law are quite different from those of long-wall mined-out area.

Interactive on-surface signal deformation [PDF]

ACM Transactions on Graphics, 2010
We present an interactive system for the artistic control of visual phenomena visible on surfaces. Our method allows the user to intuitively reposition shadows, caustics, and indirect illumination using a simple click-and-drag user interface working directly on surfaces.

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Injection‐Related Hazards in the Permian Basin as Characterized by Spaceborne InSAR and In Situ Measurements

Geophysical Research Letters
Wastewater injection in Texas has led to leakage at compromised wells and anomalous seismicity. We use Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) surface deformation maps and a suite of ground measurements to characterize injection ...
