研究了具有薄磁致伸缩(MS)、压电(PE)和衬底(Sub)层的复合材料悬臂梁在开路和短路条件下的静态弯曲模式横向磁电效应和磁场诱导弯曲响应。给出了PE、MS和子层应变耦合三层复合材料在所有层序中的解析理论。我们使用应力、应变、H、E和D场的线性耦合本构方程，给出了FeCoBSi-AlN-Si材料系统在任意厚度比下的开路和短路磁电响应和弯曲响应的结果。除了丰富的顺序依赖行为外，该理论还预测了开路和短路磁电响应之间的巨大和系统的差异，在开路情况下，在相似的MS和PE层厚度处产生极大值，在短路情况下，PE层厚度接近于零。相比之下，开路弯曲与短路弯曲的关系。
The static bending-mode transverse magnetoelectric effect and the magnetic field-induced bending response of composite cantilevers with thin magnetostrictive (MS), piezoelectric (PE), and substrate (Sub) layers is investigated for the PE layer subjected to open and short circuit conditions. Analytic theories are presented for strain-coupled three layer composites of PE, MS, and Sub layers in all layer sequences. We use constitutive equations with linear coupling of stress, strain, H, E, and D fields and present results for the open and short circuit magnetoelectric and bending responses for arbitrary layer thickness ratios for the FeCoBSi-AlN-Si materials system. Besides a rich sequence dependent behavior the theory predicts great and systematic differences between the open and short circuit magnetoelectric response yielding maxima at similar MS and PE layer thicknesses in the open circuit and near vanishing PE layer thicknesses in the short circuit cases. In contrast, the open vs. short circuit bending r...
