Quasi-1D Modeling of Polymer Melt Die Swell in Short Dies
Jae-Hyeuk Jeong, Arkady I. Leonov
This paper describes the isothermal die swell using our recent quasi-1D model for fast (high Deborah number) contraction flows of polymers melts. Because the model analyzes the flo…
The Model of Fast Contraction Flows for Polymeric Melts
Jae-Hyeuk Jeong, Arkady I. Leonov
The present paper develops an isothermal model for fast (high Deborah number) contraction flows of polymers from a reservoir to a die of circular or rectangular cross-sections. Two…
Analysis of weak elasticity of nematic solids using a continuum approach
A. I. Leonov, V. S. Volkov
This paper formally analyses effects of nematic weak elasticity using the five parametric de Gennes (DG) potential. The analysis is trivialized in a specific (local) Cartesian coor…
On the weak nematic elasticity and soft deformation modes
A. I. Leonov, V. S. Volkov
The paper investigates the general case of incompressible non-classical elasticity with small deformations and rotations. It is shown that the internal spin rotations are important…
