Understanding the deformation mechanism of amorphous polymeric materials is indispensable for their applications but is quite challenging. Here, with amorphous …
Edge fracture is a viscoelastic instability characterized by the sudden indentation of a fluid's free surface when the fluid is subjected to a high enough shear rate. During shear …

Electroconvection in electrodeposition results in fast growing ramified deposits undermining the efficacy of the process. Here we examine the effect of polymer additives in the electrolyte …
Recent models have predicted entangled polymer solutions could shear band due to unstable flow-induced demixing. This work provides the first experimental probe of the in situ …
We develop a rheological model to approximate the nonlinear rheology of wormlike micelles using two constitutive models to represent a structural transition at high shear rates. The …

In polymeric materials subject to both polymerization reactions and flow, there can be a complex interplay between reactions and stress relaxation processes. For example …
Shear banding in entangled polymer solutions is an elusive phenomenon in polymer rheology. One recently proposed mechanism for the existence of banded velocity profiles in …
