Important results from the project
The one-year long AMFat project achieved its stated goals and led to two journal papers. Characterization of surface asperities to understand its effect on fatigue life of electron beam powder bed fusion manufactured Ti-6Al-4V, Int. J. of fatigue. https://doi.org/10.1016/j.ijfatigue.2024.108516 The other manuscript is under preparation. The collaboration during the project has resulted in a new Master’s level course on Fatigue and Fracture Mechanics (UBM600) at University West.
Expected long term effects
The project AMFat has led the basis for future collaborative research on defect and fatigue life – some of which have already started at the University West. The industry project partner GKN Aerospace Sweden will make use of the learnings to continue industry research to predict life of complex aero-engine component built through additive manufacturing process. The advanced level course will help students acquire relevant knowledge on the important subject for years to come.
Approach and implementation
The short duration of the AMFat project made it mandatory to have a detail plan of the activities at the start of the project. It was possible to execute the activities without any significant deviation. The project goals were fulfilled within the original budget. However, involvement of the key participants in developing and teaching a course led to an extension of the project duration. The collaboration between industry and academic partners worked extremely well.
