| Abstract: | The Gurtin type variational principles for piezoelectric media in the coupled dynamic field were studied. Several kinds of Gurtin type variational principles and generalized variational principles for piezoelectric media were established by using the Calculus of Variations method. The results can provide the criterion for the dynamic Finite Element Method analysis model of the transversely isotropic piezoelectric media. |
