  Is considered non-stationary axisymmetric problem for fine round bimorph plate under the action of the top end surface of the normal stresses, being an arbitrary function of radial coordi-nates and time. On the basis of the theory of Tymoshenko by the method of finite integral transformations built a a new solution for the electroelasticity system stepwise  variable thickness and stiffness. The obtained relations allow to investigate the stress-strain state and the potential difference between external electrodes bimorph elements.
