加筋板结构低周疲劳寿命预报方法研究
摘要
Abstract
In this paper,stiffened plates,the basic unit of ship structures,are taken as the research object.Based on the local stress-strain method and the ε-N curve,the low-cycle fatigue(LCF)life prediction method of notched stiffened plates is studied.The effects of factors such as load amplitude and load ratio on the low-cycle fatigue life of notched stiffened plate structures were studied through experimental methods,and the test results were used as reference data to compare and verify the accuracy and applicability of different local stress-strain calculation methods and strain-life models,on which a low-cycle fatigue life prediction method for notched stiffened plate structures was formed.关键词
