Frame-invariant formulation of novel generalized Newtonian fluid constitutive equation for polymer melts
In this work, the frame-invariant formulation of a new generalized Newtonian fluid (GNF) constitutive equation is proposed. Viscosity is considered as a specific function of the second and third invariant of the strain rate tensor a...

Investigation of the predictive/fitting capabilities of the molecular based constitutive equations for polymer melts
Predictive/fitting capabilities of the XPP and PTT-XPP constitutive equations are compared in both shear and uniaxial elongational flows using two LDPE materials (Escorene LD 165 BW1 and Bralen RB 0323). Linear viscoelastic properti...

Rheological characterisation of LDPE materials by means of differential constitutive equations
For rheological description of branched LDPE melts (Escorene LD165BW1 a Bralen RB0323) the following differential constitutive equations were used: eXtended Pom-Pom, Phan Thien-Tanner-XPP, and modified Leonov models. There ...
