摘要：
In this paper, the analytical and computational homogenization of composites with generalized microstructural periodicity is presented. The role of non-linear periodicity function is established in the analytical expressions of the effective properties and clarified through the waviness effect in wavy stratified composites and through the cylindrical periodicity in fiber composites. A numerical example is presented, that validates the two-step analytical homogenization in wavy multilayered materials. Moreover, an approximate computational technique, based on locally periodic homogenization, is proposed, followed by a numerical example. (C) 2012 Elsevier Ltd. All rights reserved.
