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