Abstract: Equations for the buckling of a thin piezoelectric plate are obtained from an existing set of equations for the extension and flexure of piezoelectric plates. The equations for buckling are specialized for piezoelectric ceramic plates poled in the thickness direction. Solutions for the buckling of a ceramic plate into cylindrical shape and the buckling of a rectangular ceramic plate are obtained. The effect of piezoelectricity on the critical load for buckling of a ceramic plate is examined. Results show that the effect of piezoelectricity is not negligible.
