Theory of the highly viscous flow

30 Apr 2020 Buchenau U.

In an undercooled liquid close to the glass transition, the flow begins by many thermally activated back-and-forth jumps, structural Eshelby rearrangements of strained regions. Together, they lead at short times t to the Kohlrausch t^beta shear relaxation, with beta around 1/2, before the jumps become irreversible and the viscous flow begins... (read more)
