| Outline of Final Research Achievements |
The multiferroic materials composed of the piezoelectric and magnetostrictive materials are treated. As the porpose of this research project, the piezoelectric and magnetostrictive materials are formulated as an anisotropic and linear magneto-electro-thermoelastic materials. Considering the coupling between the thermoelastic field, the electric field and the magnetic field, the non-Fourier heat conduction and the non-local elasticity are introduced. The scale effect of a plate composed of the multiferroic materials is investigated using a three-dimensional finite element method. The exact solutions of the non-Fourier heat conduction for a homogeneous isotropic hollow cylinder are obtained and the non-Fourier effect on the temperature and thermal stress distributions is investigated by the numerical calculation.
