Strain Localization: Analog Modeling and Anisotropy of Magnetic Susceptibility

open access: yesGeochemistry, Geophysics, Geosystems, 2023
The majority of the strain in Earth crust and upper mantle is localized to the high strain zones developed at ductile‐to‐brittle condition at kilometer‐to‐micrometer scale.

Contrasting stress fields on correlating margins of the South Atlantic [PDF]

open access: yes, 2015
The “passiveness” of passive continental margins across the globe is currently under debate since several studies have shown that these margins may experience a variety of stress states and undergo significant vertical movement post-breakup.

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.

Time-dependant stability of slopes excavated in marl

open access: yesGrađevinar, 2012
The soft rock weathering is considered on the basis of criteria used in various fields such as geology, engineering geology, mineralogy, soil and rock mechanics, and geomorphology.

Application of Moving Kriging Shape Functions on Plate Problems

open access: yesNUST Journal of Engineering Sciences, 2008
The Moving Kriging (MK) interpolation was recently proposed as a superior substitution of the Moving Least Square (MLS) approximation in the construction of shape functions for the Element-Free Galerkin Method (EFGM).

Soil classification in a seismically active environment based on join analysis of seismic parameters [PDF]

open access: yesGlobal Journal of Environmental Science and Management, 2022
BACKGROUND AND OBJECTIVES: Soil or rock properties where buildings are situated play an important role in the ground shaking caused by an earthquake. The highly populated Banda Aceh city in the northernmost Sumatra is flanked by two active faults, the ...

Geological constraints for a conceptual evolutionary model of the slope deformations affecting Mt. Nuovo at Ischia (Italy) [PDF]

open access: yes, 2015
ischia island was the scenario of several Holocene slope in- stability events occurred at different scales, from shallow mass movements, triggered by meteo-climatic forcing, up to massive rock slope failures such as large debris avalanches these last ...
