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

Role of Constraint on Ductile Brittle Transition Temperature of Pipe Steel X65
Procedia Materials Science, 2014 AbstractThe brittle–ductile transition temperature (DBTT) is not intrinsic to a material but depends on the specimen type and loading mode used for the test. The influence of these parameters is related to the plastic constraint. Here the constraint is evaluated by the effective T stress obtained by the stress different method on the notch tip stress ...

A rate- and state-dependent ductile flow law of polycrystalline halite under large shear strain and implications for transition to brittle deformation [PDF]
, 2010 We have conducted double-shear biaxial deformation experiments in layers of NaCl within its fully-plastic (FP) regime up to large shear strains (γ < 50) with velocity steps.

Deformation mechanisms in nanotwinned metal nanopillars [PDF]
, 2012 Nanotwinned metals are attractive in many applications because they simultaneously demonstrate high strength and high ductility, characteristics that are usually thought to be mutually exclusive.

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

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.
