Experimental and data analysis workflow: the material under investigation interrogated with a step stress input produces a strain–time curve as output (creep). The strain–time equation obtained modelling the material with a one-element GV model is then fitted to the experimental curve to identify the lumped parameters, which characterise the material viscoelastic descriptors.
