...Ran Ao; Yunpeng Cao; Junqi Luan; Xiaoyu Han; Shuying Li; Li Yan Since the health status of gas turbine engine is difficult to quantify, which brings great challenges to health assessment and remaining useful life predictions. To solve this problem, a gray target calculation and cloud gravity center...

... life prediction model was developed in order to predict life from one loading condition (constant stress-rate loading) to another (constant stress loading). The model was verified in part via a theoretical preloading analysis. 1 Present address: Department of Mechanical Engineering, The University...

... operation, based on finite element stress analysis results. It is necessary to establish the life prediction method of these superalloys under biaxial fatigue loading for reliable operations. In this study, the in-plane biaxial fatigue tests with different phases of x and y directional strain cycles were...

.... Life prediction based on test data of this investigation shows good agreement with actual flight experience of these blades. The method of this article provides a new way to estimate the potential creep-fatigue or low cycle fatigue life for turbine blades. blades creep testing directional...
