| 摘 要： | 本文研究了Ｔ型管状接头在面内和面外弯曲循环载荷作用下的疲劳强度问题，通过将材料常数和初始裂纹尺寸作为随机变量，采用ＭｏｎＣａｒｌｏ模拟方法对疲劳寿命进行了统计分析．同时，对计算结果进行了线性回归，并与实验结果作了比较。

| Abstract: | In this paper fatigue strength of T-type tubular joints subjected to in-plane bending or out-of-plane bending load is investigated. By considering material constants and initial crack sizes as random variables and applying Monte Carlo Simulation method,we have given a statistcial analysis on fatigue life Simul-taneously,linear regression analyses of computed results are performed and com-pared with that of the known experimental data. |
