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.

EXPERIMENTAL INVESTIGATION OF THE FAILURE BEHAVIOUR OF POLYPROPYLENE COMPOUNDS FOR INSTRUMENTED PUNCTURE TESTS

Acta Polytechnica CTU Proceedings, 2018
Instrumented puncture tests according to ISO 6603-2 and ASTMD3763 were executed for five different Polypropylene compounds (talcum-, glass fibre- and elastomer modified) with specimen thicknesses ranging from 1mm to 4 mm.

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.

Tensile behavior, microstructural evolution, and deformation mechanisms of a high Nb-TiAl alloy additively manufactured by electron beam melting

Materials & Design, 2023
To evaluate the tensile behavior, microstructural evolution, and deformation mechanisms of Ti-45Al-8Nb alloy additively manufactured by electron beam melting, uniaxial tensile experiments were performed at a constant strain rate of 2.5 × 10−4 s−1 at ...

An Athermal Brittle to Ductile Transition in Amorphous Solids

, 2011
Brittle materials exhibit sharp dynamical fractures when meeting Griffith's criterion, whereas ductile materials blunt a sharp crack by plastic responses.

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 ...

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

Porosity evolution at the brittle-ductile transition in the continental crust: Implications for deep hydro-geothermal circulation

Scientific Reports, 2017
Recently, projects have been proposed to engineer deep geothermal reservoirs in the ductile crust. To examine their feasibility, we performed high-temperature (up to 1000 °C), high-pressure (130 MPa) triaxial experiments on granite (initially-intact and ...

Elevated-temperature impact toughness of Mg–(Gd, Y)–Zr alloy [PDF]

, 2013
The Charpy impact results for Mg–10Gd–3Y–0.5Zr and Mg–11Y–5Gd–2Zn–0.5Zr alloys at various temperatures showed that Mg–10Gd–3Y–0.5Zr was more sensitive to temperature. The increase in impact toughness with temperature was related to the blunt crack-tip at
