ON THE INVERSE PROBLEM IN CALCULUS OF VARIATIONS FOR PIEZOELECTRIC MEDIA——THE INVERSE PROBLEM IN DYNAMICS

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