History of ductile-to-brittle transition problem of ferritic steels [PDF]

open access: yesProcedia Structural Integrity, 2022
This paper presents a review of different approaches through history concerning DTB transition phenomenon of ferritic steels and their characterization using FM concept, from the earliest studies based on LEFM to the application of the EPFM concept. The large scattering of the experimental fracture toughness data, characteristic of all ferritic steels ...

Burial depth interval of the shale brittle–ductile transition zone and its implications in shale gas exploration and production

open access: yesPetroleum Science, 2017
Brittleness and ductility of shale are closely related to shale gas exploration and production. How to predict brittleness and ductility of shale is one of the key issues in the study of shale gas preservation and hydraulic fracturing treatments.

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

open access: yesFoods, 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
