A fundamental characteristic of viscoelastic materials is that their mechanical properties are time dependent or, in the case of sinusoidal deformation, frequency dependent. Moreover, it is often the primary objective of an experiment to analyse this time or frequency dependence and fit it with a mathematical model having one or more parameters. A number of methods have been developed for this kind of analysis. They range from very simple techniques (1, 2) to more complicated computerized procedures (3). In this paper we will be concerned only with simple graphical methods. Such methods find their greatest application in the initial stages of an analysis where they can provide a quick and easy way to evaluate parameters as well as a visual indication of how reliable these evaluations are.
