Microscopic Nonaffine Deformation Theory of LAOS in Polymers
Dario Nichetti, Alessio Zaccone
We develop a molecularly motivated framework connecting large-amplitude oscillatory shear (LAOS) nonlinearities in entangled polymers to frequency-dependent nonaffine relaxation in…
Predicting the Brittle-to-Ductile Transition in Amorphous Polymers
Valeriy V. Ginzburg, Oleg Gendelman, Alessio Zaccone
Brittle-ductile transition (BDT) is an important characteristic of amorphous (and semicrystalline) polymers. For a given strain rate, at temperatures above BDT, the polymers exhibi…
Modeling the Slow Arrhenius Process (SAP) in Polymers
Valeriy V. Ginzburg, Oleg V. Gendelman, Simone Napolitano +2
Amorphous glass-forming polymers exhibit multiple relaxation processes, including the structural α-relaxation associated with the glass transition and faster secondary relaxations…
Ultrastable 2D glasses and packings explained by local centrosymmetry
A. Zaccone
Using the most recent numerical data by Bolton-Lum \emph{et al.} [Phys. Rev. Lett. 136, 058201 (2026)], we demonstrate that ideal ultrastable glasses in the athermal limit (or ultr…
