| Abstract: |
| An uniform distribution, isotropic thin plate, on which both surface there are discrete distribution piezoelectric actuators, is considered. Under action both cross force and voltage altogether, bending of the plate is analyzed. And by means of variant voltage that is exerted on actuators, the bending of plate is controlled. According to the inverse piezoelectric effect, equivalent action of the actuators are obtained. By use to Hamilton's principle, the finite element formula of bending deformation of the piezoelectric structure is obtained. And the bending of annular plate with piezoelectric material under four boundary conditions are calculated. |
