| Research Abstract |
It is possible to make smart composite material systems which are practicable in the thermal environment by combining piezoelectric materials with structural materials. One of the characteristics of the piezoelectric polymer is to be hygroscopic. As the last purpose of this research project, the analytical solutions for the piezohygrothermoelastic problems are derived, the quantitative evaluation is done by the numerical calculations. The analysis are carried as follows.
1. The transient thermoelastic analysis of the structural materials:
The one-dimensional transient thermoelastic problem for an angle-ply laminated hollow cylinder composed of anisotropic materials without piezoelectric effects, inverse piezoelectric effects and mousture effects are analyzed under the generalized plane strain state.
2. The transient thermoelastic analysis of the functionally graded materials:
The functionally graded materials without without piezoelectric effects, inverse piezoelectric effects and mousture

effects are treated.
3. The transient piezothermoelastic analysis of the piezoelectric materials:
As analytical models, a hollow cylinder and a hollow sphere are treated.
4. The transient piezothermoelastic analysis of the functionally graded piezoelectric materials:
The analytical treatment for thermoelastic analysis of the functionally graded materials are extended to the piezothermoelastic analysis of the functionally graded piezoelectric materials
5. The transient piezothermoelastic analysis of the smart composite materials:
By using the solutions for structural materials and the solutions for piezoelectric materials, the theoretical analysis of the piezothermoelastic problem of the smart composite materials are developed.
6. Transient piezohygrothermoelastic analysis:
Transient piezohygrothermoelastic problem of a composite hollow cylinder composed of piezoelectric and anisotropic laminated materials are analyzed without the coupling between the temperature field and the moisture field, and the analytical solution are obtained. Numerical calculations are carried out, the influence of the temperature and the moisture distribution is investigated. Less
