Polymeric liquids or molten plastics deform elastically before eventually flow. The yielding is seen here to lead to inhomogeneous cohesive breakup, based on a particle-tracking-velocimetric setup. For description of the method, see "A coherent description of nonlinear flow behavior of entangled polymers as related to processing and numerical simulations", S. Q. Wang, Macromol. Mater. Engr. 125, 15 (2007).
Is this common in polymer rheology? Visit http://www3.uakron.edu/rheology/.
