摘要：
Asymptotic homogenization (AH) method has rigorous mathematical foundation and can provide an accurate solution for the effective thermal conductivity (ETC) of periodic composite materials. A new implementation algorithm based AH method predicting the ETC of periodic composite materials was presented. Compared with the original implementation algorithm, the new implementation algorithm has two advantages: Its implementation as simple as representative volume element (RVE) method. The commercial finite element analysis (FEA) software as black box is used and the ETC of periodic composite materials through several simple steps can be obtained. The new implementation of AH can simultaneously use more than one element type to discretize a unit cell, which can save much computational cost in predicting the ETC of complex structure. This work is expected to greatly promote the widespread use of AH in predicting the ETC of periodic composite materials. © 2018, Editorial Office of Acta Materiae Compositae Sinica.
