Squeezing of composite piezoceramic plate under the loading of regular normal pressure

摘要

The electroelastic boundary value problem for thin composite plate of arbitrary configuration is studied under the action of regular normal pressure. The plane deformation parallel to the direction of the piezoceramic polarization is considered. The representation of the electroelastic magnitudes through three arbitrary analytic functions with complex variable is used. Using the fundamental solution for unbounded composite plate, the integral representations of complex potentials are constructed. The mechanical and electric boundary conditions at the interface of the composite plate are satisfied. Then, the corresponding boundary value problem is reduced to a system of singular integral equations of second order with fixed singularity. The solution of the problem is obtained. Numerical results using the algorithm of the quadrature method are shown.
