| 摘要: |
| 本文提出用有机颜料着色法检测表面裂纹疲劳扩展时的尺寸和形状，其结果表明，这是铝合金薄板表面裂纹测深行之有效的方法；且对表面裂纹弹塑性疲劳扩展中的其它问题，即韧带、背表面屈服、裂纹形状变化规律和裂绞穿透点进行了研究；最后用线弹簧模型处理了疲劳数据，并得出了一些结论。 |

| Abstract: |
| In this paper a dyeing method using organic dye is presented to detect the dimension and shape of surface crack under fatique progression. The results show that it is an effective method for detecting the depth of surface crack in Aluminium alloy thin-plate. Several other problems in elastic-plastic fatique progression of surface crack. such as the yielding on back surface，the changing role of crack shape and the crack penetration points are studied. Finally the fatique data are treated by line-spring model and some conclusions are drawn. |
