摘要

基于线弹性断裂力学对油轮甲板纵向疲劳寿命进行了分析。采用了应力强度因子估计的参数化公式和Paris-Erdogan定律。腐蚀的长期影响是基于对两艘油轮检查期间测量的厚度进行拟合的回归方程来建模的。为了研究裂纹扩展控制参数的重要性，进行了参数化研究。对线性断裂力学和S-N方法进行了疲劳分析比较。

FATIGUE ASSESSMENT OF CORRODED DECK LONGITUDINALS OF TANKERS

Fatigue life of deck longitudinals of oil tankers is analysed based on linear elastic fracture mechanics. A parametric formulation for the estimation of stress intensity factors and the Paris-Erdogan law are applied. Long-term effects of corrosion are modelled based on regression equations fitted to thickness measurements made during inspections of two tankers. Parametric studies are performed in order to investigate the importance of the governing parameters of crack propagation. A comparison of the fatigue analyses performed by linear fracture mechanics and S-N approaches is presented.
