摘要
对Ｔ型管节点的疲劳试验进行分析，研究疲劳裂纹的扩展规律，用“柔度法”计算应力强度因子范围△Ｋ，确定材料常数ｃ、ｍ．提出并运用“直纷－曲线模式法”估算管节点疲劳寿命，结果与试验吻合，具有一定的实用参考价值．
The paper analyses the fatigue experiment results of T-shaped tubular joints,tryingto find the extending pattern of fatigue cracks.The range of strength coefficient △K is calculatedby flexible method. The material constants c,m are determined.Theauthors propose thestraight line-curve mode method to estimate the fatigue life of tubular joints.The calculatedresults are in coincidence with the experiment results,which show that the method is of practicaluse for reference.
