摘　　要：用复变量方法研究了横观各向同性电磁弹性固体的反平面夹杂问题 ,得到了远场均匀应力和电磁场作用下夹杂内外弹性场和电磁场的解析表达式 ,结果表明夹杂内的应力。The anti plane problem in transversely isotropic magnetoelectroelastic materials containing an elliptic inclusion is considered by using the complex variable approaches.The analytical expressions for the field variables in both the matrix and the inclusion are obtained when the stresses and the electromagnetic fields at infinity are uniform.The results show that the stress,the electric displacement and the magnetic induction inside the inclusion are constants.
