Three-Dimensional Thermo-Electro-Elastic Field in a Circular Plate of Functional Graded Materials with Transverse Isotropy

Abstract

This article presents a set of axisymmetric solutions for a circular plate of functional graded materials with transverse isotropy subjected to uniform thermal loadings on the upper and lower surfaces. The temperature field in the plate is obtained as a prior, by integration. A direct displacement method is then employed to explicitly derive the thermo-electro-elastic field induced by the thermal loadings. Numerical calculations are carried out to validate the present results and to show the effect of material heterogeneity on the distributions of the coupled field. Some interesting phenomena have been observed.
