摘要
研究了压电材料耦合动态场中 Hamilton型和 Gurtin型变分原理的逆问题。采用变积方法 ,建立了各级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 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.
