摘要
基于各向同性弹性力学空间轴对称问题的基本方程，研究了纤维与基体的轴对称界面端的应力奇异性，并给出了界面端附近的奇异应力场．研究结果表明，该轴对称界面端的应力奇异性与平面应变状态下相应模型的应力奇异性完全相同，材料对界面端附近奇异应力场的影响可用三个双材料组合参数描述．
On the basis of fundamental equations of the spati al axisymmetric isotropic elastici ty, the stress singularity at the axisymmetric interface edge of fib er and matrix and the singular str ess field near the interface edge are analyzed. The results in this paper show that the stress singula rity of this problem coincides wit h that of the corresponding plane strain problem and the singular stres s field near the interface edge ne eds three composite parameters of dissimilar materials to describe t he effect of the material properti es.
