The paper is concerned with the investigation of the transient flow regime in the start-up of the Couette simple shear motion of a viscoelastic model with non-monotone flow curve, as a function of Reynolds and Weissenberg numbers. The present paper is particularly focused in establishing a numerical procedure for the problem under investigation, based on the integral expression of the shear stress in viscometric motions, as a function of the deformation history.
