Dynamic shear flow and especially large-amplitude oscillatory shear have been a subject of
interest to investigate limitations of theoretical approximations working under the assumption
of simple shear. These studies have helped in understanding the kinematics involved in
phenomena such as stick-slip and shear banding, among others. The nonequilibrium
polymer melt, which transforms with time into the equilibrium state, provides a unique
opportunity to investigate the influence of the thermodynamic melt state on the validity of …
