Abstract
There is a growing demand for methods to estimate the effective viscoelastic response of viscoelastic composites, for their applications in structural vibration and noise control. This paper proposes a novel reformulation and numerical implementation algorithm for the asymptotic homogenization theory for predicting the effective complex moduli of viscoelastic composites in the frequency domain. In the new algorithm, an equivalent harmonic analysis is established and a double-layer elements method is proposed to solve the local problem in the homogenization process. On the basis of the new algorithm, the effective complex moduli can be obtained easily by using commercial software to serve as a black box. Numerous elements and techniques for modeling and analysis available in commercial software can be applied to complicated microstructures without mathematical derivation. The numerical examples presented show the validity of this new implementation algorithm.
Conclusions
In this paper, a novel numerical implementation algorithm of the asymptotic homogenization theory for predicting the effective complex moduli of a composite in the frequency domain is proposed. To solve the local problem in the homogenization process, an equivalent harmonic analysis is performed, and a double-layer elements method is proposed. Through this algorithm, the viscoelastic response of the composites in the frequency domain can be obtained easily by using commercial software in a black-box role. In this way, the powerful modeling and analytical abilities of the commercial software are utilized for computing complicated unit cells. The viscoelastic properties of the particle-reinforced composites, the fiber-reinforced composites, and the octet-truss lattice materials are computed with this method to illustrate the effectiveness and simplicity of this new implementation.
