Nonlinear Viscoelasticity of Rubber Materials: Payne Effect and Differential Dynamic Modulus

Abstract

Rubber materials are used normally in large deformations, that is, in nonlinear conditions. So, nonlinear viscoelasticity is important for the characterization of rubber materials. So-called Payne effect, strain amplitude dependence of dynamic modulus, is one of the examples for nonlinear behaviors in rubber materials.
