摘要: Abstract Electromechanical responses of symmetric circular laminates consisting piezoelectric layers are studied, and the influence surface interlayer electrodes involved. The traction-free on top bottom surfaces, but may be subjected to external forces at lateral edge voltages applied across certain layers. Under axisymmetric deformation conditions, an approximate model which employs Kirchhoff hypothesis incorporates charge equation electrostatic is established. Then, a closed-form three-dimensional solution generated in very straightforward manner by model. fulfills all field equations interface or conditions as well specified electric boundary conditions; only restriction that mechanical satisfied average manner, rather than point point. Thus, according Saint-Venant’s principle proposed exact interior region laminates.
