fatigue crack growth rate curve 疲劳裂纹扩展速率 ; 裂纹扩展速率曲线
A small sample method for testing fatigue crack growth rate curve of steel was presented in this paper using a formula of two-dimensional one-side tolerance factor.
应用二维单侧容限系数公式，提出了一种测定金属材料疲劳裂纹扩展速率的小样本方法。
The results show that the rate of the growth of each point on the surface crack is connected with the place of crack and the structure of nozzle, and its steady shape is some of complex curve.
结果表明：表面裂纹各点的扩展速度与其所处的位置和容器接管的几何参数有关，且其扩展平衡状态为一不规则形状。
