Abstract Scope |
The geometric design of components traditionally consider the material as a monolithic structure, therefore not accounting for microstructural gradients that occur during the manufacturing process. The resulting material design allowables are conservative and associated with large uncertainty bounds. To improve precision in the life estimates, a location-specific lifing framework is developed, which tracks manufacturing processes and retrieves microstructural information at distinct locations for use within a crystal plasticity fatigue life prediction model. These approaches are used within a model-based feature information network to link the geometric features with material’s simulation and analyses to streamline the product lifecycle management. A use case for microstructural-sensitive fatigue predictions of a dual microstructure heat treated turbine disk component is demonstrated near the bore (fine grains) and rim (coarse grains) regions. The proposed location-specific lifing framework presents new opportunities for simultaneously designing the component and tailoring the microstructures to meet the targeted performance. |
