Outline of Final Research Achievements

The fundamental theory on electroelasticity in the piezoelectric materials with D∞ symmetry was constructed. To be concrete, the constitutive equations to describe D∞ symmetry were proposed, the theoretical method to analyze the electroelastic field was developed with the aid of the potential function method, and thereby the precise profiles of three-dimensional electroelastic field for various boundary value problems were elucidated. Specifically, the significant findings to achieve the required functions and safety of sensors/actuators composed of the abovementioned piezoelectric materials were found.
