Electro-Thermo-Mechanical Homogenization of Ferroelectric Atomistic Medium
Abstract
Two-scale continuum equations are derived for heterogeneous continua with full nonlinear electromechanical coupling using nonlinear mathematical homogenization theory. The resulting coarse-scale electromechanical continuum equations are free of coarse-scale constitutive equations. The unit cell (or Representative Volume Element) is subjected to the overall mechanical and electric fields extracted from the solution of the coarse-scale problem and is solved for arbitrary constitutive equations of fine-scale constituents. The proposed method can be applied to simulate the behavior of electroactive materials with heterogeneous fine-scale structure and design new electroactive materials and devices.
