BASIC CURVILINEAR COORDINATE EQUATIONS OF ELECTROELASTIC PLATES UNDER BIASING FIELDS WITH APPLICATIONS IN BUCKLING ANALYSIS

摘要

The authors have developed a two-dimensional model for the extension and flexure response of electroelastic plates under biasing fields in a curvilinear coordinate system. Applications of the model in analyzing buckling of two circular piezoelectric plates, one single-layered and the other double-layered, are included. The analysis indicates that the piezoelectric coupling has a strengthening effect against buckling.
