Abstract
The present paper discusses a thermoelastic problem in an isotropic structural plate to which a piezoelectric ceramic plate of crystal class 6mm is perfectly bonded. When an unknown thermal load acts on the free surface of the isotropic plate, the combined plate is deformed and then an electric field is induced in the piezoelectric ceramic plate. First the unknown thermal load is inferred from the electric potential measured on the free surface of the piezoelectric ceramic plate. Next we derive a distribution of electric potential on the free surface of the piezoelectric ceramic plate which gives the prescribed normal elastic displacement on the free surface of the isotropic structural plate. Finally, numerical results are illustrated graphically.
