Reaching the yield point of a glass during x-ray irradiation

A Martinelli, F Caporaletti, F Dallari, M Sprung… - Physical Review X, 2023 - APS
A solid loaded beyond the yield stress loses its elastic properties and becomes plastic. From
a microscopic point of view, this limit corresponds to the condition where plastic regions …

Microscopic dynamics underlying the stress relaxation of arrested soft materials
