摘要：In this paper, a homogenization-based method for predicting the viscoelastic properties of layered materials is presented, and the explicit formulae for predicting the viscoelastic relaxation modulus of layered materials are obtained. The derivation process includes two steps. First, the Laplace transform is applied to the governing equation of the viscoelastic problem of layered materials, and the Laplace-transformed effective relaxation modulus of layered materials is derived analytically based on the homogenization theory. Second, the effective relaxation modulus in the time domain is obtained using the inverse Laplace transformation. A numerical example is presented at the end of the paper. (C) 2004 Elsevier Ltd.
