摘要
研究了压电材料耦合动态场中Ｇｕｒｔｉｎ型问题的变分原理．采用变积方法，建立了各级Ｇｕｒｔｉｎ型变分原理和广义变分原理，为建立横观各向同性压电材料的动力学有限元分析模型提供了依据．
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.
