论证了只要合适选择中间界面层的弹性常数，各向异性线弹性固体在远场均匀反下面剪切应力作用下三相椭圆夹杂内椭圆上仍存在均匀应力场．讨论了内外两椭圆除过其中心相同外无其它任何几何限制条件．所给出的数值算例显示出该结论的正确性．该方法为纤维增强复合材料的设计提供了一条新途径．
It is demonstrated that the uniform stress field on the elliptical inclusions of the three-phase elliptical inclusions still exists under the shear stress of the anisotropic linear elastic solid under the condition that the anisotropy linear elastic solid is suitable for choosing the middle layer’s elastic constant. It is discussed that the inner and outer two ovals have no other geometric constraints except their center. The numerical examples given show the correctness of the conclusion. This method provides a new way for the design of fiber-reinforced composites.
