| 摘 要： | 含周向穿透裂纹管道在弯曲载荷作用下，实验观察到保护常量的裂纹尖端张开角与裂纹沿周向稳定扩展量有关，根据管道的裂纹角及几何参数预测了管道的ＪＲ阻力曲线，并与实验结果进行了比较。

| Abstract: | Proceeding from the experimental observation that circumferentail crack growth inpipes with through-wall circumferential crack subject to bending loads is associated with a constant crack tip opening angle,the JR curve is predicted in terms of the pipe and crack parameters The predictions copmare with experimental results for 103mm diameter pipes containing cracks with different sizes. |
