CRYSTAL MORPHOLOGY ANALYSIS OF PIEZOELECTRIC CERAMICS USING ELECTRON BACKSCATTER DIFFRACTION AND ITS APPLICATION TO MULTISCALE FINITE ELEMENT ANALYSIS
In this paper, crystal morphology analysis was performed to reveal microstructure and texture of a typical piezoelectric material, barium titanate (BaTiO3). The insulative specimen of piezoelectric material was coated with a conductive layer of amorphous osmium to remove an electric charge, and crystal orientations in broad region were measured by mean of electron backscatter diffraction (EBSD). Then the obtained crystal orientations were applied to a multiscale finite element analysis based on homogenization theory to investigate the relation with macroscopic mechanical and electrical properties. Especially, a representative volume element (RVE) of microstructure was determined to evaluate the macroscopic homogenized properties and the microscopic localized response.
