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 statistical analysis on fatigue life. Simultaneosly, linear regression analyses of computed results are performed and compared with that of the known experimental data.
