用J积分对含穿透裂纹碳钢管道进行断裂分析

STUDY ON FRACTURE ANALYSIS OF PRESSURE PIPING CONTAINING THROUGH-WALL CRACK BY J -INTEGRAL THEORY

通过对 6根管试样的试验研究和理论分析 ,确定了含穿透裂纹 2 0 #钢管道 J积分和 JR阻力曲线的计算方法 ,使得应用

By the experimental research and analysis, the engineering methods of calculating the J -integral and J R curve of 20 # carbon steel pipe containing through-wall crack were determined, then the J -integral theory can be used to make fracture analysis on the 20 # carbon steel pipe.
