Although linear viscoelastic properties can be measured in many ways, the small-amplitude oscillatory shear test is the most widely used method. Non-linear viscoelastic properties can also be measured in many ways, but no predominant test method has emerged among experimentalists. Whereas there is a unifying theory that describes linear behaviour, there is no unifying constitutive theory for non-linear viscoelasticity. For this reason, each non-linear test reveals a different aspect of a material’s behaviour. Hence, experimentalists have designed various transient experiments to capture different features of non-linear viscoelasticity.
