摘要
作者利用目前断裂力学较成熟的理论和实验数据对钻柱疲劳失效进行了分析计算。简述疲劳裂纹的特点及形成,对裂纹扩展速率的影响因素进行分析,并对钻杆裂纹进行有关计算。
The author makes an analysis and calculation of fatigue failure of drill string by utilizing rupture mechanics theory and experimental data, summarily states the characteristics and formation of the fa-tigue crack, analyzes the factors affecting the extension rate of crack and makes some calculations re-lating to the crack of drill pipe.
