Multiferroic composite materials consisting of ferroelectric and ferromagnetic bodies enable us to control magnetic flux density by electric field and electric flux density by magnetic field. Because microscopic crystal morphology affects macroscopic material property strongly, it is necessary to design material microstructures by computational simulations. In this study, multiscale analysis method based on homogenization theory was developed to estimate macroscopic material properties with consideration of microstructure. The developed method was applied to polycrystalline multiferroic composite materials. As a computational example, the effect of microstructural volume fraction on homogenized material properties was investigated.
