| 摘 要： | 假设夹杂与基体的界面为非理想的，界面两侧的切向相对位移与切向应务成线性关系，对嵌入无限大基体的椭球夹杂与基体在本征应变场下的弹性场进行分析计算，给出了不同的界面刚度下界面处的应力分布。

| Abstract: | An infinite elastic matrix containing an elliptical inhomogeneity with imperfect interface is studied. It is assumed that there is a linear law between the tangential stress and tangential displacement jump which are across the interface. The elastic field of the medium caused by a uniform eigenstrain in the inhomogeneity is derived. The effect of the interfacial stiffness on the stress distribution around the interface is discussed. |
