Asymptotics of electroelasticity piezoceramic inhomogeneous plate with a circular hole and the thickness polarization.

Non –axis – symmetrical dynamic problem of electro elasticityfor the axially – polarized piezoceramic cylinder.

“…To describe their operation in real conditions and the enhanced functionality the need for the deeper analyses of timevarying processes without which it is impossible to understand the effect of the interaction of mechanical and electrical stress fields arises. However, existing methods of calculation of the piezoelectric elements of structures with reference to non-stationary effects are far from being perfect and most of them are approximate, but much of the research is associated with the development of numerical [1,2] and approximate [3][4][5] methods of solution and also bringing these problems to static [6,7]. In this regard, methods making possible obtaining closed solutions of unsteady initialboundary problems of elasticity theory for finite bodies in three-dimensional formulation are of prime consideration now.…”
