Paper Abstract

Most of the analysis techniques used on functionally graded piezoelectric plates consider the effects of through-thickness strains since they can be significant in thick plates. Many practical applications of such plates, however, are in the form of actuators which are not necessarily thick. A simple theory such as the classical lamination theory can, therefore, provide useful estimates of in-plane deflections and stresses in thin and moderately thick plates. This theory does not, however, directly accommodate material properties that change progressively and it is desirable to develop a method with this capability. This paper presents such an approach, formulated as an extension to classical lamination theory. Polynomial series are used to approximate the true through-thickness variation in material properties and electric field strength. The resulting mathematical problem can be explicitly formulated irrespective of the actual variation in these parameters. A comparison against results from an exact three dimensional analysis demonstrates the use and accuracy of the method.
