The structure of convective nonlinearities in polymer rheology
We derive nonlinear hydrodynamic equations for viscoelastic media using the Eulerian description for all macroscopic quantities and especially for the strain tensor. The form of the convective nonlinearities is fixed by the requirement that in the appropriate limit the hydrodynamic equations for solids have to emerge. Differences to previous descriptions are discussed.
