Review of nonlinear oscillatory shear flow notations and presentations: polymeric liquids

C Saengow, AJ Giacomin - Current opinion in colloid & interface science, 2019 - Elsevier
We review notations for, along with ways of presenting, the shear stress responses to large-
amplitude oscillatory shear flow (LAOS). We find that the Fourier loss and storage viscosities …
