本文提出了一个模型，研究磁致伸缩复合材料的有效磁致伸缩对弹性模量、磁导率、体积分数等组分参数的依赖性。该模型以双组分磁致伸缩复合材料为研究对象，选取两种组分为通用磁致伸缩材料，利用复势法解析得出复合材料的有效磁致伸缩。从该模型的分析来看，磁致伸缩复合材料大致可分为两类。一种是基体材料是非磁性的或者磁致伸缩非常低的材料，其中有效磁致伸缩与元件的磁导率无关。另一种是两种组分具有接近的磁致伸缩的情况，复合材料的有效磁致伸缩一般取决于两种组分的弹性和磁性参数以及体积...
A model is presented in this article to investigate the dependence of effective magnetostriction of the magnetostrictive composites on the parameters of components including the elastic modulus, permeability, and volume fraction, etc. Concentrating on the two-component magnetostrictive composites and choosing the two components to be general magnetostrictive materials, this model yields, analytically, the effective magnetostriction of composites by means of the method of complex potential. In terms of the analysis of this model, the magnetostrictive composites can be roughly divided into two kinds. One kind is that the matrix material is nonmagnetic or a material with very low magnetostriction, in which the effective magnetostriction is independent of the permeability of components. Another kind is the case in which the two components have close magnetostriction, and the effective magnetostriction of the composites generally depends on the elastic and the magnetic parameters of both components and the vol...
