| 摘 要： | 复合材料中,纤维与基体的界面脱粘是复合材料细观损伤的基本形式之一。复合材料界面粘结强度对复合材料的宏观力学性能有重要的影响。复合材料界面断裂韧性的定义与测试要求对圆柱界面裂纹尖端应力场的奇异性有充分的了解。本文对轴对称圆柱界面裂纹的应力奇异性采用逐步近法作了近似的分析,文中对获得的所似结果作了较深入的讨论。

| Abstract: | Interface debounding is a basic form in microstructure damage of composite. The
strength of the bounding interface effects the macromechanical nature of the composite. To
define and to measure the toughness of the interface need to understand the stress singularity
at the tip of the cylindrical interface of the crack thoroughly in advance, this paper offers an
approximate approach to analyse the singularity on axisymmetric cylindrical interface crack
gradually. In the paper, it also presents a comparatively "deep discussion on the result obtaind-ed in the analysis. |
