STUDY OF MECHANICAL PROPERTIES OF VISCOELASTIC MATRIX COMPOSITE BY MICROMECHANICS

The Eshelby equivalent inclusion method is used to study the viscoelastic problem of polymeric composite materials. The creep constitutive relations of particulate reinforced composites are investigated by Laplace transformation and the corresponding principle. The variation of the moduli of materials with time and inclusion volume fraction is given, and the theoretical prediction coincides with experimental results.
