A finite element is formulated to analyze the deflection and stresses of circular and annular piezoelectric plates underloading of applied electrical potential. The element is based on linear piezoelasticity with displacement field and electrical potential properly assumed. To obtain more accurate nodal stresses , stress recovery is applied which derive nodal stresses from the theoretically accurate stresses at Gaussin points by the least square method.
Typical example in the literature are solved by the present method , comparisons are made with those by other methods and experiments to test the validity and accuracy of the present method.
