Numerical simulations reveals the physical mechanism for the onset of the sharkskin instability in polymer extrusion process In this paper, we have studied polymer extrusion, an important process in plastics manufacturing. Often the final material’s surface is rough with semi regular grooves resembling the skin of a shark. This phenomenon, […]

We report experimental microfluidic measurements and theoretical modeling of elastoviscoplastic materials under steady, planar elongation. Employing a theory that allows the solid state to deform, we predict the yielding and flow dynamics of such complex materials in pure extensional flows. We find a significant deviation of the ratio of the […]
