| 摘要: |
| 在夹杂理论的基础上，采用自洽法导出了含分布夹杂的各向异性弹性体的本构关系和有效弹性模量的细观力学表达式。本文得到的公式不仅可以处理含缺陷和损伤的材料的有效弹性模量，而且还可处理诸于纤维复合材料等各向异性材料的理论及有效弹性模量，从而为建立材料细观结构与宏观性能之间的关系提供了理论基础。 |

| Abstract: |
| The theory of inclusion is introduced in this paper. Two meso-mechanical expressions for the constitutive relations and effective elastic moduli of anisotropic media which include distributed inclusions are derived by self-consistent method. The effective elastic moduli of materials which may include defects or damage can be obtained by the expressions. The theoretical and effective elastic moduli of anisotropic media such as fiber composites are also obtained，thus a relationship between the meso-structures and macro-properties of materials are established by the expressions. |
