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.

Numerical investigation of casing shear deformation due to fracture/fault slip during hydraulic fracturing

open access: yesEnergy Science & Engineering, 2020
The frequent occurrence of casing failure has significantly affected the development of shale gas in the Sichuan Basin. Based on engineering and geology analyses, natural fracture/fault slip leads to casing shear deformation during hydraulic fracturing ...

Scale-dependent influence of pre-existing basement shear zones on rift faulting : a case study from NE Brazil [PDF]

open access: yes, 2013
Rifting of continental crust initiates faults that are commonly influenced by pre-existing structures. We document newly identified faults cutting Precambrian units in the interior of the NE Brazilian margin to assess the effects of structural ...

Geophysical tomography in engineering geology: an overview [PDF]

open access: yesThe Open Geology Journal, Vol. 3, 30-38, 2009, 2005
An overview of the tomographic interpretation method in engineering geophysics is presented, considering the two approaches of the deterministic tomography inversion, developed for rock elasticity analysis, and the probability tomography imaging developed in the domain of potential fields methods.

Inferences on modeling rainfall-induced shallow landslides from experimental observations on stratified soils [PDF]

open access: yes, 2018
Le frane superficiali indotte da pioggia (quali soil slips o debris-flows) sono una tipologia di movimento franoso che può coinvolgere i primi 2-3 metri di terreno, in genere rappresentato da coltri di alterazione eluvio-colluviali.

Deep ductile shear localization facilitates near-orthogonal strike-slip faulting in a thin brittle lithosphere [PDF]

open access: yes, 2020
Some active fault systems comprise near-orthogonal conjugate strike-slip faults, as highlighted by the 2019 Ridgecrest and the 2012 Indian Ocean earthquake sequences.

The Contribution of Near-Surface Geophysics for the Site Characterization of Seismological Stations

open access: yesApplied Sciences, 2023
The Athenet network is the network of the Seismological Laboratory of the National and Kapodistrian University of Athens. We present the geophysical investigation that has been carried out at six seismological stations of the Athenet network for their ...

Mitigating Strain Localization via Stabilized Phase Boundaries for Strengthening Multi‐Principal Element Alloys

open access: yesAdvanced Science, EarlyView.
Strain localization along phase or grain boundaries leads to crack initiation typical of alloys. In multi‐principal element alloys, the enamel‐like microstructure is stabilized by phase boundaries. This facilitates trans‐phase migration of semi‐atomic surfaces and provides sufficient plastic space for dislocation‐mediated deformation.
