Brittle-to-Ductile Transition of Sulfonated Polystyrene Ionomers

ACS Macro Letters, 2021
This study examines the brittle-to-ductile transition of sulfonated polystyrene ionomers (SPS) with different counterions. The polystyrene precursor was unentangled and had two ionic groups per chain on average. Thus, its terminal relaxation time was comparable to the lifetime of the associating ionic groups. Three types of ionomer samples were used to

Brittle-to-Ductile Transition in Metallic Glass Nanowires

Nano Letters, 2016
When reducing the size of metallic glass samples down to the nanoscale regime, experimental studies on the plasticity under uniaxial tension show a wide range of failure modes ranging from brittle to ductile ones. Simulations on the deformation behavior of nanoscaled metallic glasses report an unusual extended strain softening and are not able to ...

Brittle‐to‐ductile transition temperature in InP

physica status solidi (a), 2010
AbstractDeformation experiments were conducted on monocrystalline InP by 4‐point bend tests as well as by conventional and depth‐sensing indentation (DSI) tests. Temperature ranges where the material exhibited a brittle or a ductile behavior were investigated with particular focus on the transition from one deformation mode to the other.

The brittle‐to‐ductile transition in microlayer composites

Journal of Applied Polymer Science, 1993
AbstractThe brittle‐to‐ductile transition in continuous microlayer composites of polycarbonate (PC) and styrene–acrylonitrile copolymer (SAN) was investigated under the triaxial tensile stress state achieved at a semicircular notch. The availability of microlayer compositions with variations in the proportion of the components and also variations in ...

Multiscale modeling of the brittle to ductile transition

Journal of Nuclear Materials, 2004
A recently introduced method of crack representation as a distribution of three-dimensional Volterra dislocations is used in conjunction with two-dimensional dislocation dynamics simulations to study the brittle to ductile transition behavior of Ferritic Steels.

The brittle-to-ductile transition in silicon

Acta Metallurgica et Materialia, 1993
In order to better understand the brittle-to-ductile transition in silicon, details of different experimental and numerical studies are discussed. In the concept of elastical stress intensity factors, experiments with four-point-bending bars are not directly comparable with experiments done with tapered-double-cantilever-beam samples.

A New Phenomenon—Brittle to Ductile Transition

2016
Most published literature analyzed the elastic modulus of silica aerogels by drawing inspiration from the cellular solids models. For example, Ashby and Gibson (Cellular solids—structure and properties. Cambridge University Press, Cambridge, 1997) describe the open cellular foam model compressive modulus to follow power law dependence on the relative ...

Transition from brittleness to ductility in SiC

Journal of Physics: Condensed Matter, 2002
Following an initial elastic strain, a crystal responds to an increasing external stress by either breaking up into pieces, or else plastically changing its shape before failure. In this paper, the different behaviours of a crystal—brittle cleavage versus ductile deformation—are briefly discussed, and the transition from one regime to the other is ...
