本文提出了自适应板结构的部分混合分层有限元模型。研究了磁电弹性层合板结构的静力分析问题。通过考虑Reissner混合变分原理得到混合有限元列式。混合泛函的制定使用横向应力，位移分量和电磁势作为主要变量。其他场通过本构方程进行后计算。数值计算结果与已有的三维解析解吻合较好。
In this paper a partial mixed layerwise finite element model for adaptive plate structures is presented. Static analysis of magneto-electro-elastic laminated plate structures is considered. The mixed finite element formulation is obtained by considering a Reissner mixed variational principle. The mixed functional is formulated using transverse stresses, displacement components and electric and magnetic potentials as primary variables. The other fields are calculated by post-computation through constitutive equations. The numerical results obtained by the present model are in good agreement with available three-dimensional analytical solutions.
