Strain rate and temperature dependence of Omori law scaling constants of AE data: Implications for earthquake foreshock-aftershock sequences [PDF]

open access: yes, 2004
Little is known about the temperature and strain rate dependence of acoustic emission AE activity (AE). Hence, we carried out a preliminary series of flow-through triaxial compression tests on porous sandstones at different temperatures and strain rates.

Engineering properties of basalt aggregates in terms of use in granular layers of flexible pavements

open access: yesCase Studies in Construction Materials, 2022
In this study, it is aimed to increase the level of knowledge about the physical and mechanical properties of basalt aggregates which is produced as crushed-stone in quarries. For this purpose, an experimental study was carried out on aggregates and test

Analysis of the Dynamic Stability of Tailing Dams: An Experimental Study on the Dynamic Characteristics of Tailing Silt

open access: yesApplied Sciences, 2023
With the improvement in tailing mining-grade requirements and in mineral processing technology, tailing materials tend to be fine-grained. Under the action of earthquakes, a tailing dam is prone to liquefaction, which endangers the safety and stability ...

Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]

open access: yes, 2003
[1] Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure.

Development of a Computer Vision-Based Three-Dimensional Reconstruction Method for Volume-Change Measurement of Unsaturated Soils during Triaxial Testing [PDF]

open access: yes, 2019
Problems associated with unsaturated soils are ubiquitous in the U.S., where expansive and collapsible soils are some of the most widely distributed and costly geologic hazards.

Experimental Study on Seismic Compression of Chinese Loess under Cyclic Direct Simple Shear Testing

open access: yesAdvances in Civil Engineering, 2022
Seismic compression is the accumulation of contractive volumetric strains in unsaturated soil from earthquake shaking. For Chinese loess, the behavior of seismic compression is extremely significant and has been recognized in historical earthquakes. As a

Correction of dynamic Brazilian disc tensile strength of rocks under preloading conditions considering the overload phenomenon and invoking the Griffith criterion

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
Dynamic tensile failure is a common phenomenon in deep rock practices, and thus accurately evaluating the dynamic tensile responses of rocks under triaxial pressures is of great significance.

Temperature induced pore fluid pressurization in geomaterials [PDF]

open access: yes, 2010
The theoretical basis of the thermal response of the fluid-saturated porous materials in undrained condition is presented. It has been demonstrated that the thermal pressurization phenomenon is controlled by the discrepancy between the thermal expansion ...

Chaos and Elliptical Galaxies [PDF]

open access: yes, 1995
Recent results on chaos in triaxial galaxy models are reviewed. Central mass concentrations like those observed in early-type galaxies -- either stellar cusps, or massive black holes -- render most of the box orbits in a triaxial potential stochastic ...
