Nonlinear viscoelasticity determined from quasistatic and dynamic tests
The dependence of mechanical properties on the excitation amplitude shows the presence of nonlinear effects. Several experimental devices, however, are not sensitive enough to detect the amplitude dependence, or measure the mechanical response on assuming ab initio a linear viscoelastic behavior. Th...

The dependence of mechanical properties on the excitation amplitude shows the presence of nonlinear effects. Several experimental devices, however, are not sensitive enough to detect the amplitude dependence, or measure the mechanical response on assuming ab initio a linear viscoelastic behavior. This paper gives an alternative procedure to determine the existence of nonlinear processes, based on the frequency or time dependence of the dynamic or quasistatic moduli and compliances. The methodology is applied to stress relaxation curves of (Formula presented) and poly(vinylchloride).
