Theoretical modelling of brittle-to-ductile transition load of KDP crystals on (001) plane during nanoindentation and nanoscratch tests

open access: yesJournal of Materials Research and Technology, 2020
KDP single crystals are widely used in inertial confinement fusion and high power lasers due to the wide transmission band, high laser damage threshold, large nonlinear optical coefficient, etc.

Quantitative evaluation of fault-caprock sealing capacity: A case from Dabei-Kelasu structural belt in Kuqa Depression, Tarim Basin, NW China

open access: yesPetroleum Exploration and Development, 2015
Based on the tests of rock mechanics characteristics and the anatomy of field outcrop, the paper analyzed the deformation mechanism of faults in anhydrite-salt caprock and glutenite reservoir in Dabei-Kelasu structural belt in Kuqa Depression, Tarim ...

Rheological transitions in the middle crust: insights from Cordilleran metamorphic core complexes [PDF]

open access: yesSolid Earth, 2017
High-strain mylonitic rocks in Cordilleran metamorphic core complexes reflect ductile deformation in the middle crust, but in many examples it is unclear how these mylonites relate to the brittle detachments that overlie them.

The material deformation modes of monocrystalline gallium antimonide (GaSb) under nano-scratching

open access: yesFrontiers in Materials, 2023
The deformation characteristics of GaSb are investigated by employing nano-scratch tests to understand the material removal mechanism during ultra-precision grinding.

Depth‐Dependent Slow Earthquakes Controlled by Temperature Dependence of Brittle‐Ductile Transitional Rheology

open access: yesGeophysical Research Letters, 2023
The discovery of slow earthquakes illuminates the existence of a strange depth dependence of seismogenesis, which contradicts the common understanding of smooth brittle/seismic‐ductile/aseismic transition as going deeper into the earth's surface layers ...

The brittle–ductile transition in single-crystal iron [PDF]

open access: yesActa Materialia, 2008
Abstract The fracture behaviour of single-crystal pure iron was studied by four-point bending of pre-cracked specimens at temperatures between 77 and 180 K and strain rates between 4.46 × 10−5 and 4.46 × 10−3 s−1. Fracture behaviour changes from brittle to ductile with increasing temperature. The brittle–ductile transition (BDT) temperature increases

Finite Element Modeling of Brittle and Ductile Modes in Cutting of 3C-SiC

open access: yesCrystals, 2021
Machining of brittle ceramics is a challenging task because the requirements on the cutting tools are extremely high and the quality of the machined surface strongly depends on the chosen process parameters.

Brittle–ductile transitions in vanadium and iron–chromium [PDF]

open access: yesJournal of Nuclear Materials, 2007
Abstract We report ongoing experimental work on fracture and brittle–ductile transitions in vanadium, iron and iron–9% chromium single crystals and polycrystals. Tests were carried out by four-point bending of pre-cracked specimens in the temperature range 77–300 K, at a variety of strain rates.
