Small strain behavior of polyethylene: In situ SAXS measurements
TL;DR: In this paper, the authors investigated the influence of the stress transmitter (ST) density and the crystallinity Xc on the local deformation of stack lamella deformation and found that the ratio elocal/emacro was a constant close to 0.5.
