Multiscale asymptotic method for the piezoelectric eigenvalue problem in periodically perforated domain

A novel multi-scale asymptotic finite element method based on the Second-Order Two-Scale （SOTS） analysis is proposed for the piezoelectric eigenvalue problem in periodically perforated domain.In this method， the eigen-functions and eigenvalues are expressed in power series of periodicity to the seco...
