Boundary formulation and numerical analysis of elastic bodies with surface-bonded piezoelectric films

The behavior of an elastic body with surface-bonded piezoelectric films is studied in this paper. The elastic body is modeled by the three-dimensional equations of elasticity, while the thin piezoelectric film is modeled by the two-dimensional equations of piezoelectric shells. It is shown that the governing equations can be written as a system of boundary integral-differential equations. These equations are solved numerically by the boundary element method in an example.
