  • Polymeric materials usually present some viscoelastic behavior.To improve the mechanical behavior of these materials,ceramics materials are often filled into the polymeric materials in form of fiber or particle.A micromechanical model was proposed to estimate the overall viscoelastic behavior for particulate polymer composites,especially for high volume concentration of filled particles.The method is based on Laplace transform technique and an elastic model including two-particle interaction.The effective creep compliance and the stress and strain relation at a constant loading rate were analyzed.The results show that the proposed method predicts a significantly stiffer response than those based on Mori-Tanaka's method at high volume concentration of particles.
