Effective Creep Response and Uniaxial Tension Behavior of Linear Visco-Elastic Polymer Composites
A micromechanics model was developed to characterize the effective creep response and macroscopic stress-strain behavior of linear viscoelastic polymer composites. The linear viscoelastic behavior of polymer was modeled by hereditary integral. The rate-dependent uniaxial tension behavior of the polymer composites can be calculated using the effective creep compliance coefficients predicted by the proposed model through the hereditary integral for the composites. Numerical examples were used to demonstrate the capability of the proposed model. All calculations were accomplished in the time domain, hence the Laplace transform and inversion commonly used for linearly viscoelastic composites are not needed in this theory.
