Summary The multiparametric models of non-linear viscoelasticity, as typified by theBird-Carreau model, are ill-posed which leads to the practical impossibility of accurately determining the parameter values. This, in turn, makes it hazardous to infer the molecular behaviour of the material although the inaccurate parameters may correctly predict the bulk material behaviour. Instead, it is proposed that models which are defined directly in terms of the measured data be employed. One such model has been briefly described and this model is also well-posed, i.e. the error does not propagate uncontrollably in the calculation when one attempts to improve the accuracy or resolution of the model.
