Abstract
Piezoelectric composite materials are widely applied to intelligence structures devices and equipments making in various kinds of complex environments and aerospace. In this paper, the two-scale asymptotic expansion of differential equations of one class of piezoelectric problem in periodic structure is given. Using two-scale asymptotic method and constructing the appropriate cell functions, we get the homogenization equation, two-scale asymptotic expansions, two-scale approximate solutions and asymptotic errors for the piezoelectric problem.
