摘要

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Mon Carlo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 analpsis on fatigue life Simultaneously,linear regression a nalpses of co m puted results are performed and compared with that of the known experimental data.
