中文摘要：
建立了含单纤维和基体的双圆柱复合材料细观力学模型，采用基体剪应力的Lame形式推导了纤维轴向应力和纤维基体间界面剪应力计算方程。分析了纤维／基体模量比、纤维长径比和纤维体积分数等细观结构参数对纤维轴向应力和界面剪应力分布的影响，并对结果进行了验证。
英文摘要：
A micromechanical two-cylinder model for fiber-reinforced composites consisting of fiber and matrix was established. The equations for calculating fiber axial stress and interracial shear stress were derived as functions of the fiber axial position by employing Lame form of shear stress in the matrix. The effects of micro-structure parameters such as fiber to matrix modulus ratio, fiber aspect ratio and volume fraction on the axial stress distribution and the interracial stress distribution were investigated. Furthermore, the results were validated.
