ABSTRACT
This chapter assumes that just as for nonelectrical shells the complete electroelastic state can be represented as a sum of two electroelastic states: the inner electrostatic state and the boundary layer. The boundary layer damps down quickly in the direction perpendicular to the edge and is described by three-dimensional electroelasticity equations. In the theory of nonelectrical shells, the boundary layer plays a secondary role and is rarely resorted to for a strict calculation of the inner stressed-strained state. The chapter shows that the situation can also be observed in the theory of piezoceramic shells but with some exceptions: the calculation should be started with the boundary layer because it defines the greatest stresses. The equations of the electroelastic boundary layer, like those of the boundary layer of nonelectrical shells, can be divided into the equations for the plane and antiplane boundary layers.
