The prediction of the mechanical and electric properties of piezoelectric fibre composites has become an active research area in recent years.By means of introducing a boundary layer problem,some new kinds of two-scale finite element methods for solutions to the electric potential and the displacement for composite material in periodic structure under the coupled piezoelectricity are derived.The coupled two-scale relation of the electric potential and the displacement is set up,and some finite element approximate estimates and numerical examples which show the effectiveness of the method are presented.
