N2 - This presentation discusses the latest developments in the field of nonlinear rheology of entangled polymeric liquids, resulting from nearly two dozens of publications from the Polymer Dynamics, Interface and Rheology Group at Akron. The essential findings are that a) entangled liquids respond to sudden startup flow elastically and undergo cohesive failure or yielding before subsequent flow is possible, b) the flow field beyond the yield point is dictated by the characteristics of the yielding process that can be strongly inhomogeneous, c) entangled liquids possess finite cohesion that can be overcome after flow cessation by internal elastic restoring forces.
