Temperature-and Rate-Dependent Fracture in Disulfide Vitrimers

Z Song, G Dong, FJ Vernerey, S Cai - ACS Macro Letters, 2024 - ACS Publications
The fracture behaviors of disulfide vitrimers are highly rate-dependent. Our investigation
revealed that the temperature-dependent fracture behaviors of disulfide vitrimers cannot be …

A physically-based hydrostatic strain energy model for rubber-like materials inspired by Flory-Orwoll-Vrij equation of state theory

C Liu, H Lu - Journal of the Mechanics and Physics of Solids, 2023 - Elsevier
In a compressible hyperelastic model for rubber-like materials, the strain energy function is

A network model of transient polymers: exploring the micromechanics of nonlinear viscoelasticity

RJ Wagner, E Hobbs, FJ Vernerey - Soft Matter, 2021 - pubs.rsc.org
Dynamic networks contain crosslinks that re-associate after disconnecting, imparting them
with viscoelastic properties. While continuum approaches have been developed to analyze …

Force-dependent bond dissociation explains the rate-dependent fracture of vitrimers

Z Song, T Shen, FJ Vernerey, S Cai - Soft Matter, 2021 - pubs.rsc.org
We investigate the rate-dependent fracture of vitrimers by conducting a tear test. Based on
the relationship between the fracture energy and the thickness of vitrimer films, we, for the …

Needle-induced-fracking in soft solids with crack blunting

Z Song, S Cai - Extreme Mechanics Letters, 2022 - Elsevier
Fracking, also known as hydraulic fracture, has been intensively studied in hard and brittle
materials such as shale rocks and ice. In contrast, little is known about fracking in soft solids …

Localization and macroscopic instability in nanoporous metals

Z Sun, T Guo, KI Elkhodary, H Yang, N Zhou… - Acta Mechanica …, 2022 - Springer
Ductile fracture generally relates to microscopic voiding and to strain localization in metallic
materials. When the void size is reduced to the nanoscale, size effects often lead to a …

Study on prediction model of cavitation erosion incubation period of duplex stainless steel surfacing layer in a benign medium

Y Bao, C Cao, B Xie, Q Song, Y Jiang, N Xu - Acta Mechanica Sinica, 2022 - Springer
In order to estimate the cavitation incubation period of duplex stainless steel (DSS) under
ultrasonic cavitation erosion (CE), this paper analyzed the loading process of material …

Unveiling the Local-To-Global Property Functions of Transient and Active Soft Matter: from Dynamic Gels to Fire Ants

RJ Wagner - 2022 - search.proquest.com
Abstract “Dynamic networks” contain bonds that may disconnect and reattach reversibly,
imbuing them with nonlinear, viscoelastic mechanical response. Their mechanical response …
