Fig.4 Borders of instability in the flow-gradient direction for G = 1, according to the model of Clarke and McLeish (dotted /me), and Criado-Sancho et al. (solid line). The CM model predicts shear-induced suppression of fluctuations, i.e., Axc >0, to the left of the dotted line and shear-induced enhancement to the right, i.e., Axc < 0. The CSJVC model predicts shear-induced suppression of fluctuations to the left of the left-most solid curve and to the right of the right-most solid curve and shear-induced enhancement between the two curves.

In the above model calculations it was assumed that the various dimensionless rheological parameters are equal at all temperatures. Clarke and McLeish [70] extended their model to include different temperature dependencies of the rheological parameters. Although many of the characteristics...
