As the composite materials and structures are widely used in aerospace, it is necessary to develop more precise and higher efficient methods to predict the mechanical properties and behaviors of the composites for application. The multiscale eigenelement method (MEM) can be implemented to analysize the periodic composite materials. This paper has reserched the MEM accuracy and mechanical behavior, and deduced the dynamics analytical solution of periodic composite materials. Compared the influence to the accuracy of different model numbers. As for the problems of multiscale eigenelement method, we put forward unit cell modal method. The results of the numerical calculation indicate the effectiveness and feasibility of the unit cell modal method.
