FIG. 2: (A) comparison between flow velocity fields for an EVP fluid in an extensional flow apparatus obtained by numerical simulation (left) and by experimental measurement (right). (B) Yield stress Trouton ratio (Try) as a function of the yield strain (εy), showing strong departure from the theoretical value of Try = 2 for εy > 0.1 (C) The yield strain can be deduced from a local asymmetry parameter (LA) measured from the velocity field in extensional flow.
