Abstract
A new model was proposed to describe the behavior of melts and concentrated solutions of polymers at high strain rates. This model is a lattice of elastic elements, which, under deformation, transform into ellipsoids, are oriented, and elastically interact with each other. The calculation results give a qualitatively correct insight into the onset of structural instability and self-organization, as it is really observed in experiments in rotational flows and extrusion of polymer melts from capillaries.
