Abstract
The subject matter of the article is a non-stationary axially symmetric goal for a round flat bimorph plate affecting end faces of electric potential which in itself is an arbitrary time function. The designed model allows to take into account the peculiarity of the electric-field pattern based on same inner electrode, which appears to be a metal support plate. The authors apply the method of finite integral transformation (based on Timoshenko's theory) to develop a new closed solution for the electro-elastic system of graded-varying stiffness and thickness under consideration. The achieved ratio design allows to further analyze frequency and stress-strain behaviour of resonant flexural piezo-ceramic converters.
