crack growth rate curve

基本解释

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。
One is the cumulative fatigue damage(CFD) theory based mainly on S-N (or ε-N) curves and the other is the fatigue crack propagation (FCP) theory based on the crack growth rate curve.
提出了一种确定海洋平台钢裂纹扩展曲线的快速方法，该方法可以综合利用以往的经验数据和当前试验数据确定表面疲劳裂纹扩展速率曲线。
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。
