A nonlinear extension of the generalized Maxwell model is proposed as a constitutive equation for viscoelastic fluids. Expressions for complex-viscosity, oscillatory normal stresses, non-Newtonian viscosity and two normal stress differences are given in terms of four parameters. Comparison is made w
