A method is suggested for calculating stresses in sheared polymeric liquids. It synthesizes Kirkwood's correlation function techniques and Fixman's formulation for the stress tensor P. The dependence of P on powers of solute concentration, in the concentrated solution range, arises from a considerat
Analytical expressions of shear stress evolution for arbitrary transient flows are obtained, based on a rate-dependent network (RDN) model as well as on a nonaffine network (NAN) model. Predictions of both models are evaluated for various step histories against experimental results on linear and bra
