Rejuvenation versus overaging: The effect of cyclic loading/unloading on the segmental dynamics of PMMA glasses
Trevor Bennin, Enran Xing, Josh Ricci +1
The acceleration of structural relaxation or physical aging by deformation, known as overaging, has been reported in experiments and simulations of polymer and colloid glasses, and…
Multi-step deformation experiment and development of a model for the mechanical behavior of polymeric glasses
Grigori A Medvedev, Enran Xing, Mark D Ediger +1
Traditional models for stress-strain behavior of glassy polymers are based on the assumption that the critical features of the stress-strain response can be explained by changes in…
Segmental Dynamics in the Strain-hardening Regime for Poly(methyl methacrylate) Glasses with and without Melt-stretching
Enran Xing, Trevor Bennin, Masoud Razavi +1
Strain-hardening is a feature of polymer glasses during large deformation, which helps to stabilize the glasses against breakage. Experimentally, little is known about the segmenta…
Overaging with stress in polymer glasses? Faster segmental dynamics despite larger yield stress!
Masoud Razavi, Enran Xing, M. D. Ediger
It is well known that physical aging of polymer glasses increases their yield stress and affects their failure behavior. Studies indicate that application of moderate levels of str…
