On A Self-Consistent Molecular Modeling Of Linear Relaxation Phenomena In Polymer Melts And Concentrated-Solutions, Arkadii Leonov
Arkady I. Leonov
This paper analyzes the linear version of the theory of ''relaxation interactions'' in polymer melts and concentrated polymer solutions proposed by Pokrovskii and Volkov in 1978, and which was subsequently developed later in many of their other publications; In these papers, the Brownian dynamics of a single macromolecule surrounded by other macromolecules was considered on the basis of the bead and spring model, and the environmental macromolecules were assumed to react as a viscoelastic liquid with an unknown relaxation spectrum. The key problem in this approach is the formulation of the self-consistency condition which delivers the equation for the unknown …

On 1d-Instabilities In Simple Shear And Extensional Flows As Predicted By Some Maxwell-Like Constitutive-Equations, Y. Kwon, Arkadii Leonov
Arkady I. Leonov
One-dimensional (1D) instabilities, some of them of new type, were found in simple shear and simple elongation for Giesekus, Leonov, and Larson viscoelastic constitutive equations (CEs) with single relaxation mode. Whereas 1D instabilities in shear flow were found for all three CEs, only the Larson model manifested some ID instabilities (and even nonexistence of solution) in simple extensional flows.
