Application of a Tensile Test Method to Identify the Ductile-Brittle Transition of Caramel [PDF]

Foods, 2022
During cutting of foods, tensile stresses in front of the blade are responsible for the separation of the material. Therefore, tensile tests can be helpful to gain knowledge on deformation properties related to pre-fracture cutting behavior as well as on

Aging‐Induced Ductile‐Brittle‐Ductile Transition in High‐Entropy Alloys and its Implications [PDF]

Advanced Science
Temper embrittlement, characterized by a dramatic loss of ductility within a narrow temperature window, is ubiquitous in conventional alloys but is not reported in compositionally complex or high‐entropy alloy systems. Here, an unexpected ductile–brittle–

Effects of temperature on fatigue crack growth rates of a low-carbon pipe steel in the ductile and ductile-to-brittle transition regions

Journal of Pipeline Science and Engineering, 2023
This study investigated the impact of temperature on Fatigue Crack Growth Rates (FCGR) of low-carbon pipe steel in both the ductile and ductile-to-brittle transition regions.

Constitutive Behavior of Olivine Gouge Across the Brittle‐Ductile Transition

Geophysical Research Letters, 2023
The bottom of the lithosphere is characterized by a thermally controlled transition from brittle to ductile deformation. While the mechanical behavior of rocks firmly within the brittle and ductile regimes is relatively well understood, how the ...

Brittle-ductile transition stress of different rock types and its relationship with uniaxial compressive strength and Hoek–Brown material constant (m i )

Scientific Reports, 2023
Rocks deformed at low confining pressure are brittle, which means that after peak stress, the strength declines to a residual value established by sliding friction. The stress drop is the variation between peak and residual values.

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

Journal 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.

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

Solid 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.

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

Geophysical 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 ...
