摘要
用测定裂纹尖端张开角（ＣＴＯＡ）的方法，获得了全尺寸穿透裂纹管试样的ＪＲ阻力曲线，并用撕裂模量法对合不同穿透裂纹长度的管道进行了弯曲断裂分析。结果表明，用测定ＣＴＯＡ获得ＪＲ阻力曲线的方法是可行的。
The J-R curve was determined with the full-scale piping specimen by measuring the crack tipopening angle (CTOA). Elastic-plastic fracture of the pipes was tested and analyzed using the tearing modulusmethod. The experimental results showed that the J-R curves are conservative and practical.
