Experimental characterization and numerical modeling of micromechanical damage under different stress states [PDF]

, 2013
The use of HSLA steels for the manufacture of automotive components is interesting from an engineering point of view. This family of steels, while possessing high strength, also has good formability and can be used in forming manufacturing processes.

Microscale cavitation as a mechanism for nucleating earthquakes at the base of the seismogenic zone

Nature Communications, 2017
Earthquakes frequently occur in the brittle-ductile transition near the base of the seismogenic zone. Using shear experiments on calcite faults, here the authors show that microscale cavitation plays a role in controlling the brittle-ductile transition ...

Constraining the long-term evolution of the slip rate for a major extensional fault system in the central Aegean, Greece, using thermochronology [PDF]

, 2006
The brittle/ductile transition is a major rheologic boundary in the crust yet little is known about how or if rates of tectonic processes are influenced by this boundary.

The influence of normal stress and sliding velocity on the frictional behaviour of calcite at room temperature. Insights from laboratory experiments and microstructural observations [PDF]

, 2016
The presence of calcite in and near faults, as the dominant material, cement, or vein fill, indicates that the mechanical behaviour of carbonate-dominated material likely plays an important role in shallow- and mid-crustal faulting. To better understand

Structural Anatomy of the Intraterrane Shear Zones in the Archean Bundelkhand Craton, North-Central India and Its Possible Linkage to Supercontinent Assembly: Insights from Field- and AMS-Based Kinematic Analysis

Lithosphere, 2022
Delineation and characterization of the intraterrane shear zones (ITSZs) are very significant in establishing suitable models to understand the tectonic evolution of continental blocks and often provide crucial information on supercontinent assembly. The

Post-depositional tectonic modifications of VMS deposits in Iberia and its economic significance [PDF]

, 2011
The original stratigraphic relationships and structure of VMS deposits are commonly obscured by deformation. This can also affect their economic significance, as shown by several Iberian Pyrite Belt (IPB, SW Iberia) examples.
