摘要
本文进行了多种“疲劳+腐蚀”模式的损伤累积试验,研究了“机械载荷”和“腐蚀载荷”的相互影响,提出了腐蚀环境作用后疲劳累积损伤的竞争模型。与试验结果的比较表明在“疲劳+腐蚀+疲劳……”的加载模式下竞争模型与试验结果吻合较好。
Firstly, the damage cumulative tests of kinds of 'fatigue+corrosive' models are carried out in this paper. Secondly, the effects of mechanical loading and corrosive loading on each other are studied. Finally the fatigue damage competitive model is put forward. The predict results of fatigue damage competitive model and test results at 'fatigue+corrosion+fatigue' mode are in better agreement.
