In this project, a combination of non-destructive inspection techniques and fatigue testing procedures will be used to characterize the defects induced during 3D printing of metallic components of aircraft engines and structures and assess their impact on the fatigue life of these components. The results of these tests will provide the data supporting numerical simulations of the fatigue damage propagation and the development of advanced material/structural analysis methods aiming at predicting the fatigue life of 3D-printed components and offering clear guidelines for their quality control.

在该项目中，将结合无损检测技术和疲劳测试程序来表征飞机发动机和结构金属部件3D打印过程中产生的缺陷，并评估它们对这些部件疲劳寿命的影响。这些测试的结果将提供数据支持疲劳损伤传播的数值模拟以及先进材料/结构分析方法的开发，旨在预测 3D 打印部件的疲劳寿命并为其质量控制提供明确的指导。
