Mesoscopic prediction on dynamic visco-elastic performance of particular reinforced composites

Dynamic visco-elastic mechanism of particular reinforced composites has been investigated by Eshelby equivalence inclusion theory. A three-parameter viscoelastic model is employed to predict dynamic shear modulus in Glass/ED6 composites. It can be concluded from the results that shear modulus, volume fraction and load frequency is closely interacted. By the μ^R vs ω, μ^I vs ω, μ^R vs f and μ^I vs f curves behaviors obtained, it can be concluded that when the load frequency occupies a high value, the dynamic shear modulus is determined by its real part and when the volume fraction is high, the variation of shear modulus is chiefly caused by the imaginary part and the real part can be regarded as constant, which will lead to the simplification of complex calculation and can be useful for solving practical engineering problems.
