Abstract :
In this paper we discuss the multiscale asymptotic expansion for a kind of general second order elliptic problem with rapidly oscillating coefficients in parallel tope periodic structure. Based on the theoretical result, i.e. the property of effective coefficient when applying isotropic scaling, we investigate exhaustively the effect of structure parameters on the effective material coefficient by numerical simulations.
