The influences of crustal extension, salt tectonics and gravity-driven deformation on the structural evolution of the Halten Terrace, offshore mid-Norway: new sights from 3D seismic data and fault analysis [PDF]

open access: yes, 2008
Normal fault zones play a fundamental role in the development of sedimentary basins and in the migration and trapping of hydrocarbons. The idealised geometry of an isolated post-sedimentary normal fault (Barnett, 1987, Walsh & Watterson, 1989) existing ...

High‐Entropy Alloy Interlayers Toward Advanced Joining for High‐Performance Structural Applications: Current Progress and Emerging Challenges

open access: yesAdvanced Engineering Materials, EarlyView.
HEA interlayers offer a versatile route for joining high‐performance structural materials. Their compositional and structural design regulates interfacial reactions, suppresses brittle IMCs, and improves metallurgical bonding. Sandwich interlayers further integrate defect healing with precipitation strengthening, enabling improved strength–ductility ...

Mineralization constraints on the origin of polymetallic (Pb, Ag, Zn, Cu, Au) deposits hosted in the metasedimentary Lajeado Group, Southern Ribeira Belt, Brazil

open access: yesJournal of the Geological Survey of Brazil, 2020
The sediment-hosted polymetallic (Pb, Zn, Ag, Au-Cu) mineralization of the Vale do Ribeira Mineral District has been known since the beginning of the 20th century, but exploration was interrupted just before the turn of the century.

Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators

open access: yesAdvanced Engineering Materials, EarlyView.
Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design

Analysis of fault networks and conjugate systems

open access: yes, 2013
Faults networks exist over a range of scales and are important for understanding the brittle deformation and fluid transport processes within the Earth’s crust.

Mitigating Creep Anisotropy and Enhancing Performance in Additively Manufactured Ni‐Based Superalloys: A Review

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing introduces pronounced microstructural and crystallographic anisotropy in Ni‐based superalloys, resulting in orientation‐dependent creep deformation and damage. This review identifies the key microstructural origins of creep anisotropy, examines their influence on dominant deformation mechanisms, and highlights processing ...

The internal structure, mechanics, and fluid flow properties of low-angle normal faults a case study from the island of Elba, Italy [PDF]

open access: yes, 2009
Low-angle normal faults have been extensively documented in areas of regional extension, in both continental and oceanic lithosphere, but their existence as seismically active structures remains controversial.

Tunneling in fault zones, Tuzla tunnel, Turkey

open access: yes, 2003
The Tuzla tunnel was excavated mainly in fault zones, shale and limestones using the conventional and shielded tunnel boring machine (TBM) methods. Fault zones in shales are brecciated and clayey, while those In limestones are of blocky structure.

Microstructure‑Dependent Phase Transformations Under High‑Pressure Laser Heating in Additively Manufactured AlCrFe2Ni2

open access: yesAdvanced Engineering Materials, EarlyView.
Additively manufactured AlCrFe2Ni2 with contrasting BCC/B2‐dominant and lamellar FCC + BCC/B2 microstructures exhibits the same pressure‐induced BCC/B2 → HCP transformation. Under laser heating at high pressure, HCP is destabilized, and a cubic BCC/B2 + FCC assemblage is recovered, while the lower‐scan‐speed microstructure transforms at a lower ...
