Abstract

A time-domain model that characterizes the nonlinear viscoelastic behavior of viscoelastic elastomers has been developed. The approach is based on the method of Anelastic Displacement Fields (ADF) and was extended to model strain-dependent material behavior. The material nonlinearities were introduced through nonlinear functions that describe the dependence of the unrelaxed and relaxed material moduli, and the anelastic strain rate on the instantaneous strains. The parameters that characterize the nonlinear material behavior were identified through harmonic strain controlled experimental tests.
