Microscopic defect dynamics during a brittle-to-ductile transition. [PDF]
Proc Natl Acad Sci U S A, 2023 Deformation of all materials necessitates the collective propagation of various microscopic defects. On Earth, fracturing gives way to crystal-plastic deformation with increasing depth resulting in a “brittle-to-ductile” transition (BDT) region that is key for estimating the integrated strength of tectonic plates, constraining the earthquake cycle, and

Brittle to ductile transition in densified silica glass. [PDF]
Sci Rep, 2014 Current understanding of the brittleness of glass is limited by our poor understanding and control over the microscopic structure. In this study, we used a pressure quenching route to tune the structure of silica glass in a controllable manner, and observed a systematic increase in ductility in samples quenched under increasingly higher pressure.

Thermal effects on fracture and the brittle-to-ductile transition [PDF]
Physical Review E, 2023 The fracture behavior of brittle and ductile materials can be strongly influenced by thermal fluctuations, especially in micro- and nano-devices as well as in rubberlike and biological materials. However, temperature effects, in particular on the brittle-to-ductile transition, still require a deeper theoretical investigation.

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 to ductile transition in cleavage fracture [PDF]
Acta Metallurgica, 1992 The problem of interpretation of fracture transition from brittle to ductile or vice versa is the subject of study. An instrumented tapered double cantilever beam (TDCB) has been developed as a definitive tool in the study of the intrinsic mechanism in single crystalline samples.

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.
