Abstract In this paper, a Direct FE2 method is proposed to simulate the electromechanical coupling problem of
inhomogeneous materials. The theoretical foundation for the proposed method, downscaling and upscaling
principles, is the same as that of the FE2 method. The two-level simulation in the Direct FE2 method may be
addressed in an integrative framework where macroscopic and microscopic degrees of freedom (DOFs) are
related by multipoint constraints (MPCs) [1]. This critical characteristic permits simple implementation in
commercial FE software, eliminating the necessity for recurrent data transfer between two scales [2-4]. The
capabilities of Direct FE2 are validated using four numerical examples,… More >
