"The predictive capabilities of three models (eXtended Pom-Pom, PTT- XPP and modified Leonov model) are tested for both steady as well as transient shear and uniaxial extensional flows of LDPE. In the second part of the paper, the modified Leonov model is employed in FEM modeling of the abrupt contraction flow and predicted stress fields are compared with the stress measurements from the flow visualization cell." . .
