Predicting the Brittle-to-Ductile Transition in Amorphous Polymers [PDF]

open access: green
Brittle-ductile transition (BDT) is an important characteristic of amorphous (and semicrystalline) polymers. For a given strain rate, at temperatures above BDT, the polymers exhibit strain softening followed by yield and strain hardening, while at temperatures below BDT, the same materials exhibit brittle failure at relatively low strains. Surprisingly,

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

open access: yesScientific 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.

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.

A Study of Mechanics in Brittle–Ductile Cutting Mode Transition

open access: yesMicromachines, 2018
This paper presents an investigation of the mechanism of the brittle–ductile cutting mode transition from the perspective of the mechanics. A mechanistic model is proposed to analyze the relationship between undeformed chip thickness, deformation, and ...

Characterizing the Brittle Fracture and the Ductile to Brittle to Ductile Transition of Heat-Treated Binary Aluminum-Lithium Alloys

open access: yesEngineering Transactions, 2015
An aluminum alloy containing 2.6wt.% Li and 0.09wt.% Zr exhibited a very low value in tensile ductility consistently prior to the peakaged strength independent of thermal treatment.

Critical Depth of Hard Brittle Materials on Nano Plastic Forming

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2008
This paper reports on ductile to brittle transition of hard brittle materials in nano plastic forming process. Formability of some hard brittle materials, i.e., glasses, silicon and quartz wafers, were examined through a specially designed and developed ...

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
