Abstract
This paper presents the thermo-magneto-electro-elastic (thermo-MEE) field in an annular plate of heterogeneous multiferroic composite medium subjected to thermal loadings uniformly distributed on the main boundaries. As a prior, the temperature distribution is determined by solving the thermo-conduction equation. Then, the direct displacement method is employed to derive the coupling thermo-MEE field. Finally, numerical calculations are performed to validate the present analysis and to investigate the influence of the material heterogeneity and the multi-field coupling. The present solutions can be readily reduced to those for circular plate upon letting the inner radius tend to zero. The obtained solutions may serve as a benchmark to various numerical codes and simplified analyzes, since no ad hoc hypothesis is adopted in the present work.
