A new formulation of non-affine motion for the network model is proposed and its applications are presented in this manuscript. The major improvement is that a finite elongational viscosity is predicted for finite elongational rates contrary to the i

The diffusive properties of acetone, dichloromethane, and toluene in natural, nitrile, and bromobutyl rubber membranes at temperatures between 273 and 313 K and uniaxial elongations between 0 and 40% were investigated. As the temperature and elongati

The effect of an external stress on the barrier properties of natural, bromobutyl, and nitrile rubber were studied using a modified ASTM permeation method. Stress-induced changes such as a decrease in the breakthrough time with mechanical elongation

The chemical potential associated with the diffusion through polymeric systems is assumed to be a function of the concentration and the stress induced by the swelling. The flux for such a model is calculated and is found to be in agreement with the e

A phenomenological model that incorporates swelling is adopted and used to solve the one-dimensional sorption problem. The model predictions are in good agreement with experimental data, involving the transport of dichloromethane, trichloroethylene,

By considering polymeric solutions to be mixtures of two fluids and by applying standard continuum arguments, de Gennes, Doi, and Milner have developed equations to describe such solutions. In the present paper, the problem of the flow of a polymeric

The deformation of nylon drops in polyethylene, with and without an interfacial agent, in an extensional flow has been studied. The presence of an interfacial agent reduces the size of the dispersed phase, and the deformation of the drop is reduced.

The drag on a spherical particle is studied for two limiting cases, namely for the rigid sphere and for the bubble. An approximate solution is found for creeping flow around a particle suspended in a shear-thinning fluid. The three parameter Carreau

The problem of the availability of boundary conditions in non-Newtonian fluid mechanics is briefly reviewed. The flow with suction over a flat plate of differential, integral, and hierarchy types of fluids is studied. It is concluded that while diffe

Analytical expressions of shear stress for arbitrary multi-rate-step flows are presented for a rate-dependent network model and for a nonaffine network model. For both models the linear spectrum is modified to account for large deformations. Predicti
