| Abstract Scope |
Titanium alloys and nickel-based alloys are widely used in aero engine disks. In these materials, it is known that anomalies such as micro texture region and dirty white spot cause a reduction in life. Since the fracture of aero engine disks can lead to serious accidents, it is crucial to understand the connection between anomalies and material fracture to be able to correctly predict the life of these disks. In this study, a crystal plasticity finite element method was used to simulate the physical phenomena occurring in materials containing anomalies. In-situ digital image correlation measurements under loading were also performed, and a fracture criterion was established based on both experiments and analyses. Therefore, a highly accurate life prediction method was developed using the crystal plasticity finite element method. Additionally, a disk-scale strength evaluation method was developed using machine learning to incorporate micro-scale information about crystal grains. |
