Based on the theories of hybrid / mixed finite element method, the generalized energy functional including stress, mechanical displacement, electric displacement, electric field and electric potential is used, with the electric - potential relations and the constitutive equations of piezoelectric materials constrained, hybrid energy functional including mechanical displacement, electric potential and stress is gained. moreover, splitting in - plane components and transverse components, the mixed energy functional in which mechanical displacement, transverse stresses and electric potential as basic variables is derived. with the use of surface stress parameters of sub - elements, the continuity of transverse stress at interfaces between layers is obtained
在回顧雜交混合有限元理論的基礎上，從包括位移、應力、應變、電勢、電位移、電場強度六個未知量的廣義壓電材料能量泛函出發，通過約束電場強度?電勢關系、應力與應變及電場強度的關系，得到僅包括位移、電勢、應力三個未知量的雜交變分泛函，利用一般層合板的雜交混合變分原理，分離面內分量和橫向分量，導出以位移、橫向應力、電勢為未知量的壓電層合板的修正變分泛函，作為壓電層合板的雜交元列式的理論基礎。 -
2. based on the muller - breslau principle, formulars of equivalent nodal loads for the curved - and straight - beam element while occuring unit relative constrained displacement have been deduced. the influence surface of the internal force for grillage has been analyzed by combining kinematic method with finite element static method, using the superposition principle applied to little deformation
